How do I fix the dcom server launcher, the computer keeps shutting down after it's been on for about five minutes?

What's turning off, your laptop or just the message about DCOM server process?

Assuming you are using Windows 7 as operating system.

You need to enable WIA - Windows Image Acquisition.

1. Windows button + R
2. Type Services.msc and press enter
3. Now find the following services
Remote Procedure Call (RPC)
DCOM Server Process Launcher
RPC Endpoint Mapper
Shell Hardware Detection

To enable those services.
Right click on them, click properties and choose automatic ( will start automatically). After all the services are started and marked for automatic start, find "Windows Image Acquisition" and make this automatic too.
Reboot your computer.

in run windows type services.msc and click ok it will open services window in services there are many windows services are there choose dcom server process launcher just double click on it will open dcom server process launcher properties in that go to recovery tab and in recovery choose the option first failure set to restart the service instead of restarting the computer set to all three option second and subsequent failure. And apply it.

Have a nice day and do not forget to rate please...!

Just putthe cd windows xp to the rom drive and re-install the windows, be sure that your priority boot will be the cd rom then continue the installation and the system will repair your program.

Please refer to manual and run system restore to system default settings as if it was from the package.

Cheers.

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.
