One important feature of Windows 10 is its Firewall that keeps a check on the incoming web traffic to your computer. It is quite likely that the RPC Server issues occur because the Firewall is blocking the response from the server. Follow these steps to alter the Firewall settings to resolve the RPC Server is Unavailable issue in Windows 10:

Step 2: Once the Control Panel window opens, make sure that the dropdown beside View By is set to Large Icons.

The next troubleshooting step to fix RPC Server is Unavailable issue in Windows 10 is to check the network settings and update the network drivers. Let us begin first with confirming the network settings:
Step 1: Press Windows + R to open Run box and type ncpa.cpl followed by Enter.
Step 2: Make a right-click on your network connection among the list and then click on Properties in the context menu.
Step 3: A new box will open where you have to locate two items and confirm if they are enabled by verifying the checkmark in the checkboxes next to them. Those parameters are:

Step 4: If they are enabled, then you will have to update your network drivers to ensure they maintain a stable connection between your network adapter and all Windows components like RPC Service.
How To Update Drivers For Network Adapter In Windows 10?
There are two ways to update drivers in Windows 10 PC: Manual and Automatic. The Manual method involves identifying your hardware make and model, search for the updated drivers on the official website, download and finally installing them on your system. As it is a manual process, you have to do everything yourself which is rather time and effort-consuming.
The Automatic method of updating drivers is by far very easy and swift as all the steps are managed by a driver updater software like Smart Driver Care. This application scans your computer and identifies driver issues like outdated, corrupt, and missing drivers. It then replaces them after taking a backup with the most updated and compatible drivers available on the internet. Here are the steps to use Smart Driver Care:
Step 1: Download and Install Smart Driver Care on your system.

Step 3: Click on the Update Driver link next to your Graphic driver in the driver issues list displayed on your screen.
Once the drivers are updated, the issue of RPC Server is unavailable in Windows 10 will no longer be a problem on your computer.
Fix 4: Modify Your Registry
Disclaimer: Registry is more or less the brain of your computer. Any wrong step could require a reinstallation of the Windows operating system with a loss of data. So make sure you understand what you have to do and follow the exact steps. Also, take a back of your Windows Registry along with creating a System Restore Point before you proceed.
Step 1: Press Windows + R on your keyboard to open the Run box and then type regedit followed by Enter.
Step 2: Navigate to the following path and then click on RpcSs to reveal its contents in the right panel.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcSs
Step 3: One of the entries under RpcSs will be a REG_DWORD named Start. Double click on it and edit the value data to 2.
Step 4: Now navigate to a different path mentioned below and click on DcomLaunch.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\DcomLaunch
Step 5: Double Click on the Start in the right panel and alter the value data to 2.
Step 6: Finally navigate to the final path and click on RpcEptMapper.
