How to Resolve “DNS Server Unavailable” on Windows PC

The DNS (Domain Name System) server stores all the domain names of websites you visit. When you search for a domain name in a web browser, it is sent to the DNS server by your router. If the domain name of the website in question is registered, it returns the corresponding IP address. Therefore, the process of downloading these websites is particularly fast.

As wonderful as this process may be, it is not uncommon for the DNS server to fail to connect from time to time. In this case, attempts to troubleshoot the web browser often lead to the error message “DNS-server does not respond.

What causes the “DNS Server Unavailable” error message?

If your internet isn’t working and you’re getting a “DNS server unreachable” error message on Windows, you may be able to find the cause.

  • Your DNS server is unavailable.
  • Your network adapter driver is incorrect
  • You have configured your network adapter for a different network.

These annoying messages can often be caused by a server failure. In this case, the DNS server is temporarily unavailable.
