The Windows Store and Universal Apps make up most of Windows 10, but sometimes you may have problems with the Windows Store programs such as Emerging issue 70008.

Emerging issue 70008 Windows 10


What is Emerging issue 70008 and why does it happen?

In this post, we’ll learn about the Emerging issue 70008 and similar issues in Windows 10 that prevent people from running Universal Windows Applications or even the Microsoft Store itself.

As far as we know, other variations or strains of the problem may also affect how the Start Menu feature is used.

A lot of Windows 10 users have reported that apps received from the Store refuse to open. Several reports indicate that the problem in question mostly occurs on Windows 10 systems that use multiple user accounts.

The problem was common enough to draw Microsoft’s attention, and the operating system vendor classified it and identified the Emerging issue 70008 error as a new problem.


What are the other similar emerging issues?

Emerging issue 70008 Windows 10 - What are the other similar emerging issues

Emerging issue 70008 can be problematic and can cause many other problems. Users reported the following problems on their computers:


  • The emerging problem 67758 is another common problem that can occur in Windows 10. However, we have already covered this issue in our article about the new 67758 release, so you should look for detailed solutions there.


  • Emerging message 6619 – This error message can sometimes appear on your computer. In this case, make sure that you have updated your system and downloaded the latest updates.


  • Emerging Issue 97275 – In some cases, this error may occur due to your antivirus program. To solve the problem, turn off the antivirus program and see if it solves the problem.


How to fix Emerging issue 70008 in Windows 10


Fix 1 – Download the Microsoft Troubleshooting Software

Microsoft is aware of this problem and has already published a solution to address it. To apply this solution, you need to download and run a diagnostic program.

After you start the troubleshooting program, follow the instructions to fix the error.

Depending on the users, this problem can be solved by creating a new user account. However, it seems that this problem occurs if you have more than one user account on your PC and if so, we recommend you to download and use the diagnostic tool.

  • Open your web browser. After the program window appears in the address bar or in the existing Google search text field you need to enter the following code: cssemerg70008.diagcab


  • In the displayed list of results, click on the first element (usually a link to the Microsoft support site). View the information on the page if you want. Finally, scroll down to the Resolution menu and click on the Troubleshooting link to download the desired file.


  • Your browser should extract and save the file on Microsoft servers. Once the download is complete, you need to click or double-click on the downloaded item to start it. Follow the instructions that appear on the screen to ensure that the troubleshooting process identifies and resolves the Emerging issue 70008 problem you encountered on your Windows 10 PC.

If all goes well, you may have to reboot your system for the changes to take effect. If the procedure is successful, you can now launch or open Universal or Microsoft Store applications without problems.


Fix 2 – Check your antivirus program

According to users (too significant to ignore), the Emerging issue 70008 in Windows 10 may sometimes arise from your antivirus program. Your antivirus program may interfere with some Windows 10 features, causing this problem.

However, you can solve the problem by simply disabling some features of your antivirus program. If this does not help, you may have to completely disable the antivirus program.

In the worst case, you may need to uninstall the antivirus program. If uninstalling your antivirus program solves the problem, the next step is to switch to another antivirus solution.

We recommend also that you perform the necessary procedures step by step to reduce any consequences or inconvenience that may arise.

  • You can start by turning off your antivirus program to see how it works. Open its application, go to its settings or menu, and find the real-time protection feature or a similar feature you want to disable. Turn on any other dominant feature to which you have access, and look at the new status of your PC.


  • As usual, you may need to reboot your system for the changes you make to take effect. If nothing has changed (which means your problem persists), you may have to go to more intrusive procedures.


  • If you strongly suspect that your antivirus program is causing your headaches, no one can blame you if you have gone uninstalled. Whatever happens, make sure that you follow the installation process correctly to make sure there are no leftovers or remnants of your antivirus program that could cause problems. At the end of the process, you will need to reboot your computer for obvious reasons.


When your computer is turned on and Windows has calmed down, you should check that you can now open and run universal applications or the Microsoft Store itself. If all goes well, you will get almost complete confirmation that the antivirus program is responsible for your problem.

But you can’t leave your system without any security or protection. Your current configuration can cause other problems, some of which are even worse than the ones you just solved.


Fix 3 – Use PowerShell

To solve the Emerging issue 70008, some users suggest using PowerShell. It is a powerful tool and if you are not careful, you can damage the operating system.

If you want to be completely safe, you must create a restore point for the system before running PowerShell. To solve this problem with PowerShell, follow these steps:

  • Emerging issue 70008 - Use PowerShell - Step 4

After running all the commands, close PowerShell and see if the problem is solved.

Few users have reported that running the first command solved the problem, so you may not have to run all the commands to solve the problem.

How to solve ERR_NAME_NOT_RESOLVED problem in 12 steps



The ERR_NAME_NOT_RESOLVED error usually appears when trying to connect to a website. When this error occurs, a message appears indicating that the web page is unavailable. You will not be able to overcome this error and will not be able to access the website.

Essentially, the ERR_NAME_NOT_RESOLVED error is caused by problems with your DNS address. Your DNS address on the Internet is blocked for various reasons, so the ERR_NAME_NOT_RESOLVED error occurs.


This Webpage Is Not Available ERR_NAME_NOT_RESOLVED


If you suddenly receive an error message saying “Error 105 (net:: ERR NAME NOT RESOLVED): Unable to resolve the server’s DNS address” while browsing, this means that the DNS lookup failed. This type of error is one of the most common errors that can occur when using the Chrome browser. And since it is a fairly common error, the solution is also quite simple.

Do you get ERR_NAME_NOT_RESOLVED when browsing in Chrome browser? Sometimes this error affects several web pages while in other cases it only affects certain web pages. In any case, this error prevents the loading of web pages. An unrecoverable name error in Google Chrome technically means that the domain name cannot be resolved. As we all know, DNS (Domain Name System) is responsible for domain name resolution, and every domain on the Internet has a name server that allows DNS to resolve domain names. If for some reason DNS cannot resolve a name server, it is because the site is unavailable: ERR_NAME_NOT_RESOLVED.

There may be several reasons for this error. In general, the error may be caused by an incorrect computer or router configuration, or a problem with the web page you are trying to visit and which may not be available. Whatever the reason, here you can try an effective solution to fix the err_name_not_resolved chrome. And I am sure that one of them should solve the problem.


What causes the “ERR_NAME_NOT_RESOLVED” error?

There are several reasons why domain name resolution may not work. One of the most common reasons is that the DNS server is (temporarily) unavailable. In this situation, if there is no record for the site you want to access in your browser’s cache or in the DNS cache of your operating system, the DNS cannot resolve the domain name. The above-mentioned address records by themselves may be a possible cause of the “ERR_NAME_NOT_RESOLVED” error in Chrome.

This error may occur, for example, when a browser tries to reply to a DNS query with a cached address if the IP address has changed during this time.

Other possible causes of this error are router problems, misconfigured Internet settings, Chrome’s prediction service for faster page loading, malware, and faulty security software.


What does the error message “ERR_NAME_NOT_RESOLVED” mean?

If you received an error message “ERR_NAME_NOT_RESOLVED“, Chrome reports that it was unable to find the IP address that matches the domain name of the site you entered.

In this case, you will not be able to access the site because the IP address is required to connect to a web server.

This error may occur regardless of whether you are using Chrome on your desktop (Windows, macOS, or Linux) or mobile device (Android or iOS).

This error is not limited to Chrome; it may also occur in other browsers such as Firefox or Safari. However, you will get another error message from Google Chrome if DNS cannot resolve the domain name when you try to access the website.

DNS PROBE FINISHED NXDOMAIN: 9 guaranteed solutions to the chrome problem

If your Chrome browser reports an error saying “This web page is not available“, it is because of the DNS PROBE FINISHED NXDOMAIN error. Here you will have the guaranteed steps you need to take to fix this error on your Windows 10 computer.



When you try to access a website by entering its name, your computer’s web browser uses the help of a DNS server to find the IP address of the website you are trying to access.

For example, if you type youtube in your Chrome browser, the DNS server automatically returns to Chrome the IP address ( of that site.

However, sometimes the DNS server does not provide this information to Chrome, which leads to DNS error messages.

The DNS PROBE FINISHED NXDOMAIN error code in Windows 10 is essentially trying to tell you that the DNS lookup failed when the Chrome browser tried to access the desired website.



The DNS_PROBE_FINISHED _NXDOMAIN problem starts because the IP address does not match the DNS computer. More technically, DNS translates all messages of the target domain into an IP address.

The real problem occurs when someone enters a URL into their browser; finding a server with the corresponding server IP depends on the DNS. In general, the search process is redirected to the target site, but if DNS does not work, it will cause errors. In this case, the browser will display an error message “DNS_PROBE_FINISHED_NXDOMAIN“.

The message “NXDOMAIN” is an abbreviation for “Non-Existent Domain“. This error occurs very often and there are effective solutions for the same error. Usually, different browsers offer different solutions which will work depending on the connection to the server. For example, in Google Chrome there is a message “This site can’t be reached“. In the case of Firefox, the message will be “Hmm. We’re having trouble finding that site“.


What is DNS and why does this error occur?

DNS is an abbreviation of the Domain Name System, which is responsible for matching the IP (Internet Protocol) address with the domain name. As a rule, we use a domain name to visit a website (for example, In fact, it is the IP address that allows us to successfully visit the site. Each domain name has a valid IP address (for example, one of’s IP addresses is We use a domain name instead of an IP address because the domain name is easier to remember.

Every time you enter a domain name in your browser, DNS looks for the IP address of the domain name and returns the result. If DNS finds the IP address, you can successfully visit the website. If DNS does not find the IP address, you may get DNS errors such as “DNS_PROBE_FINISHED_NXDOMAIN“.



As mentioned earlier, the DNS_PROBE_FINISHED_NXDOMAIN error is caused by a problem with the domain name system, usually because the user’s computer cannot resolve or translate the IP address of the target website. This error is very similar to the “DNS server isn’t responding” problem. If you encounter a temporary DNS error, you will also encounter the INET_E_RESOURCE_NOT_FOUND error.

The computer uses the DNS defined in your router or modem. Usually, this is the DNS of your ISP (Internet Service Provider). In most cases, using a public DNS server will be the most effective choice. However, the problem may also be due to a wrongly configured HOSTS file.

Due to this problem, the user may be denied access to some or all of the web pages. In this situation, it is difficult to understand the meaning of the error and its cause. Many users start looking for answers to the Internet; however, users almost are never given detailed instructions with pictures.

Fortunately, we have prepared a detailed explanation of how to fix the error code: DNS_PROBE_FINISHED_NXDOMAIN in chrome.


  • TIP: One thing we recommend is to try to access another site first. If you find that you can access other sites but not a specific site, the problem may be on the other end and not with you. If so, you may have to wait for a while and try again later.


How to fix DNS PROBE FINISHED NXDOMAIN browser error?

Fix #1: Check your antivirus

If you received the DNS_PROBE_FINISHED_NXDOMAIN error in Windows 10, the problem may be related to your antivirus.

To solve the problem, we recommend you to change the configuration of your antivirus and disable some of its functions. If this does not work, the next step is to completely disable your antivirus program.


Fix #2: Use the Command Prompt

1.) Press the Windows + X keys to open the main user menu. Select the Command Prompt (Admin) on the menu.


2.) When the Command Prompt opens, type the following texts and press the Enter key:

ipconfig /flushdns


3.) When the process is complete, close the Command Prompt and make sure that the problem is solved.

If the flushdns command does not fix this error, you can also try the following commands:

  • ipconfig /all
  • ipconfig /renew
  • ipconfig /release
  • ipconfig /flushdns
  • netsh int ip set dns
  • netsh winsock reset

Fix #3: Use Google’s Public DNS

1.) Click the network icon in the taskbar and select a network from the list.


2.) Then click on the Change adapter options.


3.) Now, locate your network connection and right-click it, and then choose Properties from the menu.


4.) Select the Internet Protocol Version 4 (TCP/IPv4) and then click the Properties button.


5.) Select Use the following DNS server addresses option and type as the Preferred DNS server and as Alternate DNS server.


6.) Once you’re done, click the OK button.

Your DNS will be changed, and hopefully, the issue should be resolved.


Fix #4: Reset your Chrome to default

3.) After restarting your DNS client, close the Services window and make sure that the problem is solved.


Fix #6: Disable your VPN software

Many users use VPN to protect their network privacy, and while VPN clients are extremely useful, they can sometimes cause some problems with the DNS.

To solve this problem, it is strongly recommended to temporarily disable your VPN client and see if it solves the problem.

If disabling your VPN client does not solve the problem, you may need to remove the VPN client from your PC temporarily. Users have reported problems with the Cisco AnyConnect Secure Mobility Client, but almost any VPN client can cause this problem.

To completely remove the VPN from your PC and avoid any problems in the future, we recommend you to use uninstall software to remove it.

If you are not familiar with it, the uninstaller is a special application designed to remove programs from your PC. Besides uninstalling programs, this application also removes all files and registry entries associated with this program. So it will be as if the application has never been installed on your computer.

If the problem is solved, you can try to enable the applications individually or in a group. This way, you can find and remove the problem extension.

When you find the problem extension, remove it from your browser, leave it off or update and see if it solves the problem.

In most cases, the NXDOMAIN FINISHED PROBE DNS error is caused by security or privacy extensions. So first turn them off and see if it solves your problem.


Fix #9: Update your browser

1.) Open your Chrome browser and click on the menu icon.

DNS PROBE FINISHED NXDOMAIN - Update your browser - Step 1

2.) From the menu, select Help > About Google Chrome.
3.) Now you will see the information about the version of Chrome, which you use. If updates are available, they will be downloaded automatically.

Once your browser is updated, check to see if there is still a problem. If the problem persists after upgrading to the latest version, you should think about upgrading to a beta or canary version of Chrome.

New versions of browsers offer new features and bug fixes, so it’s always a good idea to use them.

DISM failed: absolute fix to the Windows 10 error


In this topic, we will talk about DISM Failed which is a common error in Windows 10. Deployment Image Service and Management or DISM is an integrated tool that allows network administrators to prepare, modify, and restore system images, including the Windows Recovery Environment, Windows Configuration, and Windows PE (WinPE). However, you can also use this tool to solve common problems related to the hidden image recovery of your computer.

If your device does not start up properly, has performance problems, or if you need to fix a specific error, you can usually use the System File Checker tool to scan and replace missing or damaged system files using a hidden recovery image in your installation.

The only caveat is that the SFC tool will not work if one or more files in the Windows 10 image are corrupted. If you are in this scenario, you can use DISM to restore the “install.wim” image and then use SFC to restore the installation without having to reinstall the operating system from scratch.


What Does DISM Do

The Deployment Image Servicing and Management Control Tool provides three options for Windows 10 image recovery, including Check Health, Scan Health, and Restore Health, which you want to run in this order. Depending on the severity of the problem, you can also use special settings with the Restore Health option to restore a locally available image using different source files.

In this DISM Failed Windows 10 fix, we will look at the steps to use DISM and SFC tools using a command prompt to restore your device.

Important: Although these are non-destructive commands, you will make changes to the system. It is recommended that you make a temporary full backup before you get started.


The most common error messages for DISM Failed and why it happens:


      1. DISM failed no operation was performed
      2. DISM failure when attempting to copy boot files
      3. Error Code 87, 112, 11, 50, 2, 3,1726, 1393, 1910, etc.
      4. Dism.exe failed validating command line, to load wim manager
      5. DISM failed while processing command cleanup-image, add-package
      6. DISM failed 0x8000ffff, 0x800f0954, 0x800f081f: The Source File Couldn’t be Found
      7. DISM failed to load the provider, to unload offline registry, to flush file buffers, to set the windows directory, mount the image

We execute a DISM command to recover damaged system files. This is therefore a very important command for diagnosing problems with Windows PC error. If a DISM failure occurs, several error messages may appear. However, the solutions are very common.


How to Fix DISM Failed

Solution 1: Check your Antivirus or Security Software

Antivirus software installed on your computer can cause many problems (e.g. compatibility problems and file loss). Unfortunately, it will also cause a DISM Failed error. Antivirus software in the security program is able to interfere with your system and any critical process.

Therefore if possible, I advise you to disable all antivirus/protection programs or remove them temporarily and then repeat the DISM scan to see if it works.

  • If this has helped solve the problem of DISM not working, you should consider modifying the antivirus software or disabling the security features.
  • If this method did not help, it means that the DISM error has nothing to do with the antivirus software and you should continue to see other methods.


Solution 2: Execute DISM Command in “Clean Boot” Mode

This method works when a DISM fails due to a service conflict.

  1. Open the Settings application by clicking on windows and selecting settings (you can also open it by pressing Win + I directly).
  2. Scroll down and select update & security.
  3. Switch to the recovery option on the left pane.
  4. In the right pane, look for the “advanced startup” section. Then click the “restart now” button below it.
  5. Select troubleshoot in the Select Options window.
  6. Select advanced options, then click the command prompt.
  7. Select your account to continue.
  8. Run a DISM command (for example, DISM /Online /Cleanup-Image /Check Health) and you will see it.

DISM Failed - Execute DISM command in clean boot


Solution 3: Specify/Change the Correct Location for the Install.wim File

When you get the source files could not be found error, you need to check the location of the install.wim file. Under these conditions, you will need the help of a boot floppy (or at least a system ISO file).

Important: the DISM command is case sensitive; before executing the command, you should make sure that each word is spelled correctly.

How to specify the correct location for the install.wim file:

  1. Keep a boot disk at hand (if it is an ISO file, you should create a boot disk with it).
  2. Open the Windows search window and type cmd.
  3. Right-click on the command prompt and select run as administrator, remembering the letter of the boot disk.
  4. Enter this command in the command line window: DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:F:\Sources\Install.wim:1 /LimitAccess (* is the boot media drive letter). Then press the “Enter” key on your keyboard.
  5. Wait for the command to finish.

Network change detected: 10 complete Windows 10 bug fixes

If you receive the error “Network Change Detected, Your Connection Was Interrupted, ERR_NETWORK_CHANGED“, you are not alone.

Network Change Detected - Your Connection Was Interrupted - ERR_NETWORK_CHANGED

Internet access can sometimes be tedious. If you use the Internet, you probably found the error “ERR_NETWORK_CHANGED” in the Google Chrome browser. Or maybe you are just experiencing this problem and looking for a solution to fix this Chrome bug.

Most users reported this bug with the “Unable to access network” bug as well as the “ERR_NETWORK_CHANGED” bug. This prevents them from browsing through their Internet connection. Users have also linked this error to Google Chrome’s browser, as it is most often displayed in this browser.

Since this error can occur in all web browsers (Chrome, Edge, Firefox, and Internet Explorer), we will focus on Windows issues that cause these errors. It is unlikely that the error will occur in your browser.

  • Important: This guide applies to Google Chrome on Windows 10, Windows 8 or Windows 7 computers and notebooks.


Why does the “Network Change Detected” Error Appear?


In my experience, Chrome triggers this error when it detects that your computer’s IP address has changed. As you may know, each computer on your network must be assigned a unique IP address to connect to the Internet. Based on this IP address, your Internet service provider or the owner of the site may restrict access to sites.

One of the main reasons for changing your network is that your Internet connection goes through another tunnel. Usually, use VPN or proxy servers to change the IP address of your computer to get around these restrictions. Using public DNS also speeds up the domain resolution process and provides a location name that matches the IP address of the server.

Obviously, this is an error when connecting to the Internet. During my research I found that these are the main reasons:

  • Frequently connect/disconnect from the Internet.
  • Use a proxy server.
  • Any software that affects DNS settings.
  • Third-party extensions.

What does “err_network_changed” mean?

Most people may be curious to know what err_network_changed means and what it does with the Chrome browser.

Default gateway not available: 6 detailed solutions for Windows 10 error

When we surf the Internet and explore websites, we often encounter a problem connecting to the Internet, and when we try to find the cause, we get a warning that the “default gateway not available“. Now let us know what it means and how we can fix it in Windows 10.

What is the default gateway?

The default gateway is a router or network node in a computer network system that acts as a transmission leap to another network system if the routing table does not specify the IP address for the next-hop to transmit a packet to the target node.

Thus, the default gateway serves as an access point to other networks when one network wants to communicate or send data packets to another network. This includes changing the IP address and subnet mask of the system and network topology.

In general, each of the components on each network supports a routing table that specifies the port or interfaces to be used for communication, the rules to follow, and the route by which specific data packets will be delivered over the network.

If an IP packet, in any host instance, does not find a suitable set of rules and routes to deliver the packet to its destination address, it selects the default gateway for the rest of the routing process.

Therefore the default gateway is defined by a set of specific configurations known as the default route. In small offices or home networks, the router connecting the local network to the Internet acts as the default gateway for all network components.

Reasons for the “default gateway not available” error

You may have a connection problem with limited Wi-Fi access. When troubleshooting the network the error “The default gateway not available” is displayed and the problem is not solved. You will see a yellow exclamation mark on the Wi-Fi icon in the system tray and you will not be able to access the Internet until the problem is solved.

Default gateway not available in Windows 10

The main reason for this error seems to be damaged or incompatible network adapter drivers. Outdated router settings and drivers may also cause this problem. Some users have reported that McAffee security solutions can sometimes block your connection. In some cases, this error can also be caused by malware or viruses, so we need to solve the problem completely. So, without wasting time, let us see how to actually fix the “default gateway not available” in Windows 10, using the solutions below.

One of the reasons for showing that “default gateway is not available” is the McAfee security program installed in the PC. Hence, to remove this problem go to the control panel of your PC, then enter programs and then go to program and features option.

From this option go to add or remove program option and select McAfee and then completely uninstall it.

After you uninstall this program, your issue will be resolved. To make your system virus free, you can install some other security product.

Release your current IP by typing the following ipconfig /release and then press enter. This will release any assigned IP addresses and gateways from your computer.

Next you need to type in ipconfig /renew to get a new IP address or default gateway. On the screen your should see your new Default Gateway and IP Address. If you are using a router or your IP has not changed on your modem then the addresses may not have changed.

Your default gateway is on the same subnet as your computer, and is the gateway your computer relies on when it doesn't know how to route traffic.

If you don’t have a gateway your network communication have no problem. But you cannot communicate with other networks. That means your packet will not reach other networks.

How do I completely uninstall Veeam Backup and Replication?

Use programs and components to uninstall Veeam Backup and Replication.

When a new program is installed on your system, it is added to the list in the “Programs and Components” section. If you want to uninstall a program, you can delete it in the “Programs and Components” section. If you want to uninstall Veeam Backup and Replication, you must first uninstall it in the “Programs and Components” section.

Incompatible Veeam Backup version for Office 365 Server

This error occurs after downloading Veeam Explorer for Microsoft Exchange and trying to connect to VBO server. The error is a bit misleading because it is actually a version of Explorer and not the VBO server itself.

If you look at the zip file downloaded from VBO v3, you will see three installers.

The simple solution is to install a new version of the Explorer. The Dead Gift is a new home screen.

When the process is complete the restart of the Explorer session will be successful and you will see a list of mailboxes that have been backed up.

Reconnect the SQL Server Connection

All VAC data is stored in the main SQL Server database. For this reason, it is crucial that the connection between the VAC service and the SQL database is always guaranteed. There may also be situations where we need to change these connection settings, such as B., when we switch from one deployment type to another.

In all these cases, we are in a situation where the settings are stored in the database itself, but the database itself is not available. However, VAC has a special option to log into the console without logging into SQL to restore or modify it.

When we try to connect to the VAC, when the connection to the database is lost, we may get the following error:

This message is deliberately general in nature, because we want intruders not to brutally force the login screen to find out if SQL is unavailable, if the user is present, and so on. Д.

As administrators, we can restore an SQL connection using the following procedure:

  1. Log on the server where the VAC service is running.
  2. Stop the VAC service using the command line:
    stop VeeamManagementPortalSvc
  3. Run VAC in easy mode using the command line:
  4. Run VeeamManagementPortalSvc Lightweight
  5. Log in locally (or via remote desktop) on a computer with VAC web user interface.
  6. Open your browser and specify the URL https: // localhost: 1280.
    NOTE. Do not use the link created by the installer. This leads to the full domain name (FQDN) of the server which does not allow the connection. Registration should take place through the localhost interface.
  7. Log in to the user interface with a user who is the local administrator of a Windows computer running the VAC service. In the Simplified Mode, local administrators can still log on to troubleshoot database connectivity issues. In a distributed installation, if WEB01 is a web interface server and VAC is a VAC server, we need to connect to VAC \ Administrator.
  8. We are now connected to the VAC in Maintenance mode:
    As we can see there are only two possible operations and the default is to change the SQL connection settings. After fixing and saving this problem, the maintenance mode will be disabled and the SQL connection will be restored correctly.

NOTE: If we have configured the VAC theme to use a color other than blue by default, we will find that the maintenance mode will also revert to this color, because the parameter is also stored in a database that cannot be viewed . When the user interface returns to the color of our choice, this is a quick sign that the SQL connection has been restored.

The Veeam Backup & Replication console does not open when the hostname is changed.

If you change the host name for a computer with Veeam Backup & Replication installed, the console may not open with an error (see next screenshot):

The Veeam Backup service is stopped. An attempt to start the Veeam Backup service causes a problem.

While logging, the Veeam Backup service is trying to connect to SQL using the previous hostname. % programdata% \ Veeam \ Backup \ Svc.VeeamBackup.log:
The [database] information connects to SQL Server (CurrentUser = [NT AUTHORITY \ SYSTEM], ServerInstance = [<OldHostname> \ <SQLInstanceName>], Options = [Direct]).
Information [DB | Error] Failed to connect to the server.

To solve this problem, update the product configuration by specifying the current hostname using the following steps:

  • Open the Configuration Database Connection Settings program, which should be displayed in the “All Programs” menu of Veeam Backup & Replication server.
  • In this program, select Veeam Backup and Replication and click Next.
  • Find the server name. This field is formatted as follows: <Hostname> \ <SQLInstanceName>.
  • Change the first part of the server name to match the current host name of the Veeam Backup & Replication machine, and click Next.
  • Veeam connects to the database. Wait until this process is complete and click Next. The Veeam service shall be started.
  • When this is done, click Finish and try to log into the Veeam Backup & Replication console.

How to Specify Veeam Catalog Service Port

Veeam Backup Catalog is a function that means indexing the guest files of virtual machines. Veeam Backup Catalog includes Veeam Guest Catalog services that run on the following backup infrastructure servers: Veeam Backup Server and Veeam Backup Enterprise Manager Server.

  1. The Veeam Guest Catalog service on Veeam Backup Server works as a local directory. It collects index data for backup jobs on a particular Veeam Backup Server and stores this data locally in the Veeam Backup Catalog folder.
  2. Veeam Guest Catalogue Veeam Backup Enterprise Manager acts as a federal directory service. It interacts with Veeam Guest Catalog services on Veeam Backup Servers connected to
  3. Veeam Backup Enterprise Manager and performs the following tasks:
    1. Replicate index data from Veeam backup servers to create a federal directory.
    2. Store index data
    3. Allows you to search your computer’s guest operating system files in backup files.

Specify Service Ports

The step of the port setup wizard is available if you have manually configured the settings.

Specify the HTTP and HTTPS port numbers and select the certificate that will be used by Veeam Backup Enterprise Manager. This certificate is necessary to establish a secure connection to the Enterprise Manager website using the HTTPS protocol (standard port 9443). The Veeam plugin for the vSphere web client and the RestAPI client also uses this certificate to retrieve data over HTTPS.

The High Security Mode option disables the use of weak encryption to communicate with the computer on which Veeam Backup Enterprise Manager is running. This may affect the operation of third-party software installed on the same computer.

You can configure the values of port numbers used for communication between backup infrastructure components:

  1. Catalog of service ports. The directory service port is used by Veeam Guest Catalog Service to replicate directory data from backup servers in Veeam Backup Enterprise Manager. By default, port 9393 is used.
  2. The Veeam Backup service port. The service port is used by Veeam Backup Enterprise Manager to collect data from backup servers. In addition, Veeam Backup & Replication Console uses this service port to connect to the backup server. By default, port 9392 is used.
  3. The port of secure connection. The secure connection port is used by the mount server to connect to the backup server. The default port is 9401.

Verify and Check Global Catalog Port

At this step, the port through which the connection to the virtual machine with the “Global Catalog” role is established is checked.

You can override the following parameters for the Check global catalog port step:

Critical Step – Yes
Determines whether the virtual machine recovery phase is critical.
If you mark this step as critical, failure of one virtual machine in a critical group of virtual machines will interrupt the plan.

Server – %current_vm_ip_list%
The name of the server to be checked.
Note. It is necessary to use DNS name or IP address.

Port – 3268
Port number to verify access to LDAP GC service.
Location – Veeam Backup Server (not available for editing)
Determines whether the script runs on Veeam Backup & Replication server, VAO server or guest virtual machine.

Timeout – 300
Maximum time (in seconds) to perform a step.

Retries – 10
The number of attempts if a step has failed at the first attempt.

Failback & Undo Failover Action – Skip
Determines whether this step will be performed during the recovery operations after failure and rollback.

Test Action – Execute
Determines whether a step in DataLab is performed while testing the plan.

Performing Catalog Replication and Indexing

After performing backup tasks with indexing of the guest operating system file system enabled, perform directory replication to merge index files from multiple backup servers. During this process, Veeam Backup Enterprise Manager collects index data from multiple backup servers and stores it on Veeam Backup Enterprise Manager for viewing and searching files.

Veeam Backup Enterprise Manager provides two options for directory replication:

  • To perform directory replication manually, open the Options tab in the configuration view and click Update Now on the Search in Catalog tab.
    • Open the Options tab in the Configuration view to automatically start directory replication after each backup task.
    • On the Catalog Browse tab, select “Automatically update directory after each backup task” and specify other options if necessary.

Each launch of a directory replication task triggers a new task session, which can be followed on the “Sessions” tab in the configuration view. To view detailed information about a particular session, select it from the list of sessions and click the link in the “Status” column.

A Guide to Veeam Setup Best Practices

More and more companies realize that server virtualization is the way to modern data security. In 2020, VMware is still the market leader, and many Veeam customers are using VMware vSphere as their preferred virtualization platform. But backing up virtual machines in vSphere is only part of the service availability. Backup is the backbone of recovery. So it’s important that backups are always available at the right speed.

This guide presents Veeam Backup & Replication best practices. It is not complete documentation or a detailed explanation of the features. The Best Practices Guide is for professionals looking for answers and suggestions on various topics. It may be a design idea, the best way to use a function, possible pitfalls, etc. D. As a rule, this information has been developed, collected, and updated by the Veeam Solutions Architects team working on site with Veeam users. They do not explain theory, but practice.

Note that the best practices are not the only available answer. In most cases it will work, but it may be completely wrong in other circumstances. Make sure you understand the recommended best practices, or ask someone to do so.

K.I.S.S. design

It becomes more difficult for the IT department to manage and ignore too complex projects, and it is easier for an intruder to use them and stay in the background. Projects that are easier and easier to ignore are usually safer. Use the K.I.S.S. (Keep it simple stupid) Principle for your creations. KISS is an acronym for “Keep it simple, stupid” as a design principle established by the US Navy in 1960. The principle of KISS states that most systems work best when they are simple and uncomplicated. Therefore, simplicity should be a key design objective and unnecessary complexity should be avoided. Simple design is easier to control and is generally safe.

Adding security to an existing infrastructure is much harder and more expensive than thinking about designing a new infrastructure or upgrading an existing one. In a virtual infrastructure, it makes sense to create a master image that has been enhanced from the beginning. Remove all known attack vectors and access only when Veeam components are added and certain (port) openings or additional software are required for correct operation. Thus, all versions are consistent and up-to-date, which makes them safe in the database.

Make sure that the repository servers are physically protected.

Place the repository servers in a restricted area, because these servers contain a 100% copy of your production environment! The repository servers must be physically secure and have appropriate access control systems. This will restrict access. All those who have access are logged and controlled at certain defined levels.

Use a standalone Windows server

If you are protecting the entire environment, you do not want the Veeam repository to be associated with the same Microsoft Active Directory domain that you are protecting through a backup. Otherwise, you may have a chicken and egg problem with accounts trying to authenticate to a domain that is no longer available if everything is lost.

If the domain administrator account is compromised, we do not want that account to be able to override the password for the backup store account so that the hacker can access the backup files as well as the entire environment.

Protect physical or external cloud servers with Veeam Agent’s backup.

  1. You may have servers that Veeam cannot back up or replicate.
  2. Maybe physical servers or a virtual machine that is in a public cloud that you do not have access to a hypervisor (e.g. AWS),
    Azure-blue). For these servers, you can back up the iland cloud repository using Veeam Agent.
  3. Backups. This agent is installed in the guest operating system of the production server and does not require access at hypervisor level. Veeam Agent can be installed on Windows and Linux systems.

Note the bandwidth availability.

  1. The performance of Veeam Cloud Connect is highly dependent on the available bandwidth. For example,
  2. If you are trying to back up or replicate terabytes of data, but only 20 Mbps is available, you can
  3. Backing up should take a few days. The initial backup or replica may be important time, because all data has to be transmitted for the first time.
  4. When you can’t finish Timely progressive work can have a significant impact on your safety and confidentiality.
  5. It is also better to schedule external tasks outside working hours if possible. This allows you to allocate Veeam bandwidth instead of sharing it with your network end users.

Check your backups and replicas regularly.

The worst time to find out if your backups or replicas are damaged is when you need them. Check yours.
Backups and copies for replication to ensure that they are complete and acceptable when and how you do it
you need them. You can use Veeam Console to restore all VMs, VM files or guest OS files to your computer.
Surroundings. This process gives you confidence that your data will be available immediately if
There is a disaster.

  1. You can test the failover at any time and access your replicas in the iland cloud.
  2. This is useful not only to test the integrity of your replica data, but also to provide access to and
  3. The function works as it should. It may be necessary to update the existing network rules.
    or that new critical servers have been added to production but not yet replicated.

Physical deployment


In small to medium sized environments (up to 500 virtual machines), Veeam Backup and Replication Server, Backup Repository and Backup Proxy components are typically running on the same physical server. This is also known as deployment of a “model device”.

In large environments (over 2500 virtual machines), Veeam’s backup and replication services work best on separate physical or virtual servers. When multiple jobs are running at the same time and consume large amounts of CPU and RAM, it may not be possible to scale up a virtual backup and replication server to meet system requirements.

One of the advantages of running Veeam Backup and Replication Server on a physical server is that it runs independently of the virtual platform. This may be an ideal situation where the virtualized platform is recovering from a disaster.

In an enterprise environment, you can install additional VBR to speed up the disaster recovery process. You can reuse existing availability components, such as a repository or proxy server, for Veeam Backup and Replication.

Backup Proxy

The Backup Proxy is a compact architectural component of Veeam that sits between the data source and the backup destination, processing backup jobs and providing backup traffic. Backup proxy server tasks include retrieving VM data from the production storage and compressing, deduplicating and sending this data to the backup repository. With more than one virtualized (or physical) backup proxy, you can easily scale your backup infrastructure to fit your system size.

  • In a simple deployment scenario for small environments, Veeam Backup Proxy is automatically installed on the VBR as part of the Veeam Backup and Replication installation.
  • In advanced deployments, the Proxy role is manually assigned to one or more Windows servers. This offloads the Veeam backup server, reducing backup time and improving performance.
