The RPC server unavailable error may restrict access to certain files, but it is easy to resolve.
For people who know little or nothing about networking, the Windows 10 “RPC server is unavailable” error seems overwhelming.
But with some adjustments, you can easily correct the error. Before repairing, users should understand the meaning of this error. When a Windows computer cannot communicate with other devices on the same network, an RPC server unavailable error occurs. This may be due to incorrect configuration of your firewall or interference from third-party software.
Here’s how to fix the RPC server unavailable error in Windows 10.
1. Restart the RPC Server
The most efficient way to resolve this error is to restart the service. This will cause Windows to reestablish all connections and call all processes.
- In the Start menu search bar, type Control Panel and open it.
- Click on Administrative Tools and subsequently select Services.
- Look for DCOM Server Process Launcher and double click on it.
- Ensure that “Startup type” is set to Automatic and “Service status” is Running.
- If there is any discrepancy, set the “Startup type” to Automatic and click Start below “Service status.”
Restarting the computer is the solution to many Windows problems, and is usually a great first choice before delving into more serious solutions.
2. Clean Boot the Computer to Rule Out Third-Party Applications
The “clean boot” is a boot state in which all third-party software and services are disabled. Although this is not an automatic feature built into Windows, it is quite easy to do. Many users report that the “RPC server is unavailable” error is caused by a problematic third-party application.
To use this as the cause of the error, you need to clean up your computer startup:
- In the Start menu search bar, enter sysconfig and open System Configuration.
- Go to the Services tab and check the Hide all Microsoft services button.
- Subsequently, check all the services from the list and click on Disable all.
- After this, open Task Manager via right-clicking on the Taskbar and selecting Task Manager.
- Go to the Startup tab and click on each service one by one and click Disable.
- Exit and restart the computer.
Try to use your computer to see if the error reappears. If it is not, it means that the error is caused by interference from a third-party application. It is best to uninstall the most recently installed application and download a different version.
3. Check Your Network Connection Settings
If you cannot open a specific file or folder with File Explorer, your network settings may not be configured correctly. Follow the steps below to enable the ideal option for your network:
How to Configure Your Network
- Press Windows Key +R to open the Run command. In the dialog box, type ncpa.cpl and press Enter.
- Right-click on the relevant network connection. For example, if you’re using Wi-Fi, right-click on Wi-Fi.
- Then click on Properties. Administrator privileges will be required to do so.
- In the Properties menu, enable the File and Printer Sharing for Microsoft Networks and Internet Protocol Version 6 (TCP/IPv6) options.
If this does not solve the problem, the user can also try to reinstall the network driver. This will cause Windows to download and install the network driver again, which can solve the problem. To do this, follow these steps:
How to Uninstall Network Drivers
- Press Windows Key + R and type devmgmt.msc in the Run dialog box.
- The Device Manager will open.
- Navigate to the Network adapters option and expand it.
- Right-click on the network drivers and click on Uninstall.
- Close all windows and restart your computer.
4. Change Your Firewall Settings
Windows Firewall can sometimes block RPC server traffic, resulting in “RPC Server Unavailable” errors. In this case, users must reconfigure their firewall settings to allow traffic.
For third-party firewalls, the steps may be different, but this is how to reconfigure the Windows firewall:
- In the Start menu search bar, enter Control Panel and open it.
- In the Control Panel search bar, type “firewall.”
- Under the Windows Firewall option, click on Allow an app through Windows Firewall.
- In the dialog box, look for Remote Assistance and check all the boxes.
- Save changes and restart your computer.
5. Change Registry Settings
Before attempting this repair, be sure to create a restore point and back up your registry. If none of the above fixes helped resolve the error, it may be worth reviewing your log to verify the error values and correct them.
To do this, follow these steps:
- Press Windows Key + R to open the Run dialog box.
- Type regedit to open the Registry Editor.
- Navigate to:
- Double click on the Start entry and set “Value data” to 2.
- Navigate to:
- Double click on Start value and change “Value data” to 2.
- Navigate to:
- In the Start value, set “Value data” to 2.
If you can’t find these registry keys, you may need to reinstall Windows or use System Restore to recover your computer. For users who do not have a restore point, it is better to configure Windows to create a restore point every day to avoid such accidents in the future.
6. Use System Restore to Restore Your Computer
If the user has tried everything on the list but still can’t resolve the error, it might be time to use System Restore. If you enable system protection, Windows generally creates a restore point automatically or when you install new software.
To use System Restore, follow these steps:
- In the Start menu search bar, type Control Panel and select the Best Match.
- In the Control Panel search bar, enter “recovery” and click on the Recovery option.
- Click on Open System Restore in the Recovery window. You’ll need administrator privileges to do so.
- Click on Next, then select a restore point from the list.
- Click on Finish.
After this, Windows will automatically restart your computer to a previous state.
Bid Farewell to the RPC is Unavailable Error
It is obvious from the fixes listed above that this bug is not particularly difficult to resolve. But it prevents users from opening or modifying certain files, causing panic.
After completing these simple steps, you will resume operation immediately.
