How to Fix Windows 10 RPC Server Unavailable

In this article, I will discuss how to fix the Windows 10 RPC server unavailable issue.

Overview of the Issue

To fix the Windows 10 RPC Server Unavailable issue, first, check your network connection and ensure that it is stable. Next, restart your computer to see if the problem resolves itself. If not, try disabling your firewall temporarily to see if it is causing the issue.

If the problem persists, check if any recent updates or changes have caused the problem. You can also try resetting the RPC service by going to Services in the Control Panel and restarting the service.

Updating your Windows system to the latest version can also help resolve RPC Server Unavailable errors. Additionally, running a system scan using the Windows built-in tool can help identify and fix any underlying issues.

Understanding RPC and Its Functionality

RPC (Remote Procedure Call) is a protocol that allows a program on one computer to request a service from a program on another computer in a network. This functionality is essential for communication between different systems, such as when troubleshooting issues like the “RPC Server Unavailable” error on Windows 10. To fix this error, you can start by checking that the RPC service is running on your computer. You can do this by opening the Services window, locating the “Remote Procedure Call (RPC)” service, and ensuring that it is set to “Automatic” startup type.

If the service is not running, you can start it manually by right-clicking on it and selecting “Start. ” Additionally, make sure that the Windows Firewall is not blocking RPC communication by allowing the necessary exceptions.
