Have you gotten an RPC error lately? They look a little like this:

– “RPC Server is Unavailable”

– OR “The RPC Server is too busy to complete the task”

– Here’s the best one, “Access denied”

This is fun stuff. Unfortunately, an RPC error is one of the most common errors out there, and most of us don’t even know what RPC is.

What is RPC?

RPC stands for “Remote Procedure Call.” This probably still doesn’t tell you much. Let’s see if we can put this in non-technical language. RPC is the go between of your computer and server. This is what allows your computer to access a network.

RPC has two main parts to it: the client and the server. When the client (the program requesting something) sends a message to the server (the process that takes the order or performs the task), it is being asked to execute a certain procedure. The client waits for the server to process the call before resuming the execution.

Why Won’t the RPC Server Work?

Usually, the RPC error pops up because there is some sort of miscommunication between the computer and the server. Most of the time, the wires get crossed somewhere due to Internet components that are not configured or activated. Sometimes it is just a matter of adjusting the Internet Firewalls or Proxy Server.

Quick RPC Error Fix

One way to investigate an RPC server error is to verify that you have enabled the DCOM Tunneling is enabled and not being blocked by any third party Internet Security programs such as AVG, Norton, McAfee, etc.

To do this:

1. Go to Start and Run

2. Type in DCOMCNFG

3. Click on Component Services

4. Click on Computers

5. In Computers, right click My Computer

6. Choose Properties

7. Go the Default Properties tab

8. Check the “Enable DCOM” tab

9. Go to the Default Protocols tab

10. Click Add

11. By the Protocol Sequence move the down arrow to Tunneling TCP/IP

12. Click OK

13. Click MoveUp button until Tunneling is at the top of the list

14. Now you may select SPX and Remove

15. Click OK or close the program out

16. Restart the computer

When You Need Help with the RPC Error

The RPC Error is such a common error, it seems like it should be easy to fix. However, the DCOM Tunneling fix is only the beginning of troubleshooting an RPC server error. The good news is that you really don’t have to do anything when it comes to an RPC error if you maintain your computer with registry maintenance tools. Try researching the benefits of a registry cleaner to fix RPC errors.
