Com surrogate is a service that allows switching on the com ports. Without it, communication to your devices will stop. If you're encountering this error there is a driver problem with your com port controller and you need to install the correct drivers.

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.

Hello sans_sankar,

If it says RPC server is unavailable, that has to do with your internet connection.

Check if both ends of your ethernet or USB cable are properly plugged in their ports on your modem or router to your computer.

You can also turn the modem or router off for a minute then turn it back on again.

Your video installation should be complete, otherwise, it might be incompatible with your computer.

Hope that helps.


Yours truly,

Are you trying this in safe mode?
Sometimes the RPC service will refuse to start. Assuming all other services are reset to their default values:

Start, run, CMD

net start (check the service again to be sure it is stopped)

net start rpcss
net start (check again)

if no joy, you need to use the XP CD to go to the Recovery Console.

From the Recovery Console type:

enable RpcSs SYSTEM_AUTO_START

reboot the machine.

"Could not start the Remote Procedure Call (RPC) Service. Error 1058" error message when you manually start the Remote Procedure Call service

Some general things to try.

See if System Restore will get you back to a restore point before your problem with Explorer.

Try Safe Mode (Do you have this problem in Safe Mode?).

Try running ChkDsk to check your drive for errors. Right-click your Drive icon/ Properties/ Tools/ Error Checking. Select both boxes.

Run the System File Checker program from the Run Box by typing.....Sfc /Scannow in it and have your XP CD handy.

The computer displays error "RPC Server is unavailable".
It may be that you have a static value in your registry's field PagedPoolSize, we need to make this "0" (zero). check the steps ->HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Could be a corrupted file in your spooler folder:

hi! Print Spooler is actually a service for your Operating system-
Try this

Click on start and click on run
in the open box type in services.msc and your services local window should open, scroll down and look for print spooler, highlight it and do a right click and on the dropdown menu left click on stop and it will go to a process of stopping the service and then right click back and click on start. if you get an error message about print spooling or spooler, then that means you have a problem with the operating system. call or go to microsoft help and support online in that case. and RPC server unavailable error has something to do with a network printer. but i believe you setup the printer locally.
