So here are a few ways that can help you to fix the RPC Server Unavailable Error in Windows, have a look:

How To Fix RPC Server Is Unavailable Error In Windows

1. Ensure Your RPC Services are Running Properly

The first thing that you need to figure out after seeing the RPC Server Unavailable Error on your screen is to ensure your RPC services are running properly. It can be caused due to the improper functioning of RPC service on every computer connected.
To check whether or not the RPC services are running properly, you need to follow these steps:
  • Press the Windows + R key on your keyboard to open the Run dialog
  • Now type services.msc and press enter
  • scroll down on the services window to find the DCOM server process launcher, Remote Procedure Call, and RPC Endpoint Mapper.
  • See if their status is running and their startup is set to automatic
If their status is running then it means they are functioning properly. On the other hand, if they are not running then you can change the status. If they are not set to automatic, then you can go to the registry (method 4).
After you have checked everything, and all is well, and you can’t understand the problem then you might need to go for the next solution.

2. Check the Firewall on Your Computer

Since Firewalls can be a reason behind the RPC Server Unavailable Error then you would need to work on it as well. Firewalls can often block the traffic requested by the RPC which can further result in the communication problem. So you should check the Firewall configuration and see if it is the one blocking the network connection for RPC. The process can be different for the inbuilt antivirus and the third party firewalls, so if you are using the third-party firewalls, you would need to follow these below-mentioned steps and see if that is the reason behind the error.
These are the steps that would work for the Windows Firewall:
  • Press Windows Logo Key + R Key at the same time on your keyboard to open the Run dialog window.
  • Now, type Control and press Enter on your Keyboard.
  • This would open Control Panel on your Windows
  • Next, you will need to search for Windows Firewall on Control Panel
  • Click on the Allow an App Through Windows Firewall below the Windows Firewall
  • Now, scroll down to find the Remote Assistance. See if its communication is enabled.
  • If not, then allow them the remote assistance
This should be able to resolve the RPC Server Unavailable Error if the Firewall was the cause of the problem and if not, then move to the next option.

3. Check Your Network Connection

Another one of the reasons behind the RPC Server Unavailable Error is the poor network connection or if there is something that I’d caused some kind of barriers in the network connection. If your network connection is not set properly then it could lead to the unavailability of the RPC Server. You need to make sure that it is fixed and there is no flow in the network connection that connects your computer to the server.
To check the network connection, you need to follow these steps:
  • On your keyboard press the Windows logo key + R key at the same time to open the Run dialogue on your computer
  • Once it is opened, type ncpa.cpl and then press Enter
  • Right-click on the network you are using, it will open further options
  • Now select Properties among those connections
  • Make sure File and Printer Sharing for Microsoft Network and Internet Protocol Version 6 (TCP/IPv6) are enabled (see if the boxes present next to them are checked)
You can also reset the network connections by reinstalling your network adapter driver. There are also other drivers that you can use which would detect, download, and install the driver update on your computer automatically. This would help you to scan your computer, be it the network connection or the driver updates.

4. Check Your Registry

The next thing that you need to do to resolve the RPC Server Unavailable Error is to check the registry. By checking the registry you would find whether or not your RPC is working properly.
{Note: editing the Registry can cause some serious changes in your computer. This can lead to unexpected problems in your computer so we strongly recommend you to create a system restore point and back up your registry before you proceed}
If you have taken all the precautionary steps, then you need to proceed and check the registry.
Follow these steps:
  • Log in to your Operating system as an administrator
  • Press the Windows logo key + R on your keyboard to open the Run dialog then type Regedit and press enter
  • Now that your registry is opened, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcSs
  • See if there are any items that don’t exist ( among the items given below in the picture). If there is, then reinstall the Windows
  • If the RPC was not correctly set (as was given in method 1) then you need to edit the registry
  • Start registry key in RpcSc path. Double click on Start to edit its Value and Set its value data to 2
Repeat the navigation with the RPC Endpoint Mapper and DCOM Server Process Launcher and set their Value to 2 as well.
This might help you to fix the RPC Server Unavailable Error, if not then move to the next solution.

5. Switch to ChromOS

Windows is one of the best Operating systems that you can find, but if you are the one that needs a faster and more relevant OS that can be up to date with the technology and allow you to install as many third-party apps without compromising with the security or the overall performance of your PC then you may want to switch to ChromeOS.
