Users who have been using systems such as Windows 10 for a long period of time may have encountered an issue where the RPC server becomes unavailable. In this case, you will most likely not be able to properly connect to other devices on your network.

This problem can limit your ability to share files, use printers, and exchange data or information over the network. Today, we’ll look at what you can do to fix the “RPC server unavailable” error on Windows operating systems.

Simply put, an RPC server allows you to exchange data over a network and send information to another device. RPC allows you to manage devices such as printers and scanners on that network.

If the RPC server becomes unavailable, you lose this functionality. This error can have several causes, the most common of which are listed below.

What are the reasons for the “RPC server is unavailable” error message?

One or more services required for RPC are disabled: In most cases, this problem occurs when one (or more) of the required services is disabled on one or more of the computers involved in the connection. If this scenario applies, you can resolve the problem by using the Services utility to force the disabled services to run.

Remote Assistance is disabled by the firewall: The Windows firewall and some other third-party counterparts are known to block connection to remote assistance by default. If this is what caused the problem, you can solve it by setting an exception for this type of connection.

IP address crashes the RPC server: A non-unique IP address can also cause this particular error message. If this scenario applies, you can solve the problem by clearing the IP address and then updating it.

RPC services disabled through the registry: Some utilities or manual user intervention may cause some services required by the RPC server to remain disabled. Users in a similar scenario reported that the problem was resolved after using the registry editor to force the services used by the RPC component to start.
