Fix: ‘RPC Server is Unavailable’ Error in Windows

However, those of you guys who have been using Windows for subsequently probably have already bore witness to the “RPC Server is Unavailable” error. This is a too common error which you guys can run into whilst using the Windows OS & often causes confusion to more inexpert Windows users as to why it appeared in the first place.

You need not fret, though, as it is not a serious or dangerous error. Though all of your programs & data are secure. The RPC stands for is Remote Procedure Call, though which is a process that some apps will use to communicate with other apps that are running on the same PC.

What this means is that RPC permits different procedures to communicate with one another just to perform a task. 'RPC Server is Unavailable'

Furthermore, it works similarly to networking in that the RPS server will open a port, gage a reaction from the goal service or server, send a packet at a time a response is received. Then transfer the task data to the goal service or server. Just after the job is completed, the complete process operates in reverse simply to send data back to the starting program.

An RPC Server Error Has Occurred

RPC server errors are not exclusive to the Windows OS nor only a single PC. However, the RPC process is also used on most recent operating systems. The purpose for an RPC error will normally occur on one PC. But the cause probably actually be found on a complete network. Fortunately, in this article, we will be looking into both possibilities.

So what entirely causes an “RPC Server is Unavailable” error? When one service on your PC has to communicate with another, it will contact the RPC server on your PC to initiate the exchange.

However, the RPC server will also open up a few ports to listen for a message & issue one back. Whether the RPC server fails in order to get a response, is unable to write to memory, unable to open a port, or is simply unavailable, then the error is triggered.

Fixing RPC Server Errors

Similarly, there are three methods in order to go just about resolving one of these errors on a PC running Windows 10. Though the most usual of the three would be that the RPC service is not even running. The other two, problems with the network or corrupted registry entries, are less likely but probably still occur.

When you receive one of these errors, or any Windows error really, the first thing to try is a full reboot. A reboot will fix a temporary issue related to the RPC server. If a reboot doesn’t resolve the error, you’ll want to dive into one of the fixes below.

RPC Service Not Running

After a restart, check to see whether the RPC Service is causing the issue.

  1. Now you have to head to the Task Manager by right-clicking on the Task Bar and choosing it from the list.
  2. Here you guys have to navigate to the Services tab & then Open Services.
  3. Drop to the Remote Procedure Call service. So it should be running & set to Automatic. Whether it is not, change it.
  4. Here navigate to the DCOM Server Process Launcher. Similarly, this too should be running & set to Automatic. Again, whether consequences are different, make the essential changes.

Network Problems

Problems with TCP or your firewall can prevent RPC from working. This is true even just whether the call is created internally on your own PC as the RPC Server still utilizes the network stack for communication causes.

  1. Stop the Control Panel & here you must choose the Network and Internet (view by set to Categories) or 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. The IPv6File and Printer Sharing for Microsoft Networks should both have a checkmark. Whether they don’t, add it and tap OK & retry the task that caused the error. Whether they are already marked, next you guys will also need to check your firewall.
  4. Choose the Windows Firewall in Control Panel.
    • For third-party firewalls, you will have to test with the settings. You should provide it at a time over but do not change anything whether it is a firewall you have been using for a whilst.
  5. Now locate Remote Assistance and confirm it is enabled for DomainPrivate and Public networks. Then save any conversions you have made.

Registry Corruption and Complications

Whether everything has been fine up to this place, then the last thing you guys are also able to take a look at is the registry entries that handle the RCP & DCOM services for corruption. I do not suggest tinkering with the registry, especially for starters, so to be safe and secure, we are heading to back up the registry before messing with anything.

  1. Here first of all you have to Enter regedit into the search box on the Task Bar. Now tap on Registry Editor when it appears.
  2. Tap Computer from the left side window & head to the File tab. Choose Export from the menu.
  3. Here select a name and location for the saved file & must hit the Save button.

At a time when a backup of all registry files also has been created, you guys are also able to check the entries for the RPC & DCOM services.

Now navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RpcSs 

In the right pane, now right-click Start & then Modify… Simply set the value to (2).

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

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

Do the exact thing with Start as was completed in the previous step.
