How to Fix the Error in Windows “RPC Server is Unavailable”

RPC Server is Unavailable

Many people of you who have been using Windows may have already borne observer to the “RPC Server is Unavailable” error. However, this is one of the more usual errors you are able to run into. Whilst using the Windows OS and often causes confusion to more untrained Windows users as to why it popped up in the first place.

RPC Server is Unavailable

Although you need not worry, about (RPC Server is Unavailable) as it is not a very serious error. Because all of your programs and data are safe. What RPC stands for is Remote Procedure Call, which is a procedure that some applications will use to communicate with other applications that are running on the same PC.

Similarly, what this means is that RPC permits different procedures to communicate with one another in order to perform a task.

It operates similarly to networking in that the RPS server will open a port. And measure a reaction from the destination service or server. Send a packet at a time a response is got and then transfer the task data to the destination service or server. After the job is completed, the whole procedure operates in reverse to send data back to the launching program.

An RPC Server Error Occurred

 

RPC Server is Unavailable

Although RPC server errors are not exclusive to the Windows OS nor just a single PC. The RPC method is used on most current operating systems. Similarly, the reason for an RPC error will normally occur on one PC. But the reason may actually be found on an entire network. Fortunately, in this guide, we will look into both possibilities.

Therefore, what exactly causes an “RPC Server is Unavailable” error? When one service on your PC requires you to communicate with another. So that it will contact the RPC server on your computer to initiate the exchange.

Similarly, the RPC server will open up a few ports in order to listen for a message and issue one back. Whether the RPC server fails to get a response, is not able to write to memory. That cannot open a port or is simply unavailable, then the error is activated.

Solving the RPC Server Errors

Three methods are there to go about fixing one of these errors on a PC running Windows 10. So the most common of the three would be that the RPC service is not even running. Similarly, the other two, problems with the network or corrupted registry entries, are less likely but may still occur.

Therefore when you get one of these errors or any Windows error. So the first thing that you have to try is a full reboot. A reboot will fix a temporary problem related to the RPC server. So if a reboot does not resolve the error. Then you will desire to follow the fixes mentioned below.

RPC Service is Not Running

Although after a reboot, you have to check to view whether the RPC Service is causing the issue.

  1. First of all, you have to head to the Task Manager by right-clicking on the Task Bar. Then choose it from the list.
  2. Navigate to the Services tab and then Open Services.
  3. Now drop to the Remote Procedure Call service. So it should be running and set to Automatic. If it is not, then you have the ability to change it.
  4. Then navigate to the DCOM Server Process Launcher. However, this too should be running and set to Automatic. Again, if results are different, create the essential conversions.

Network Issues

Problems with TCP or your firewall are able to stop RPC from functioning. So this is true even if the call is made internally on your PC. As the RPC Server still uses the network stack for communication causes.

  1. Here first of all you have to pull up the Control Panel. Then change Network and Internet (see by set to Categories). Alternatively, Network and Sharing Center (set to either large or small icons).
  2. Tap the Ethernet link located next to Connections: Then Properties in the popup window.
  3. Simply the IPv6 and File and Printer Sharing for Microsoft Networks should both have a checkmark. However, if they do not, then you have to add it. Then tap OK and retry the task that caused the error. Whether they are already marked, then you will have to check your firewall.
  4. Choose the Windows Firewall in Control Panel.
  5. Here you should adjust the Remote Assistance. And then confirm that it is turn on for DomainPrivate and Public networks. Simply then save any conversions you have made.

Registry Corruption and Complications

Although if the whole has been fine up to this point. Next, just the last thing that you are able to take a view at is the registry entries that control the RCP and DCOM services for corruption. I do not suggest tinkering with the registry. Especially for the newcomers, so to be safe, we are going to back up the registry before messing with anything.

  1. First of all, make an enter regedit into the search box on the Task Bar. Then tap on Registry Editor when it appears.
  2. Similarly, then tap the Computer from the left side window and open the File tab. Then choose Export from the menu.
  3. Select a name and location for the saved file and hit the Save button.

At a time a backup of all registry files has made. So you can easily check the entries for the RPC and DCOM services.

Now you should navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcSs 

In the right pane, right-click Start and then Modify… Set the value to (2).

Then, you will have to navigate to both the keys below:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\DcomLaunch
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcEptMapper.

Similarly, now you have to do the same thing with Start as was finished in the prior step.
