Rpc service unavailable

Answer 1

I made the costly mistake myself, in turn I have learned that if you are attempted to disable services on you Windows XP you should create a secondary hardware profile*

and make changes to it instead. Back Up registry, and any information you would not want to lose. The RPC service if disabled in the hardware profile will prevent you from being able to paste, or send data to removable drives, prevent you from updating windows, prevent you from using Windows Installer, prevent you from transfering data over your network to/from that PC. Basically wreak havoc on your world.

1. Check to see if service is started

Start-> Run-> services.msc

RPC service and select start

2. Select RPC service in msconfig

Start-> Run->msconfig->services tab->enable all Microsoft services

3. Back Up registry back

Click on File-> Export->Select somewhere where you can find it like My Documents->Click Save

4. Click+ HKey_Local_Machine -> Click+ System-> Click+ CurrentControlSet->Click+ Services-> Click on RpcSs folder-> Right click on Start in the right pane-> Select modify-> change value to 2-> Click ok-> Exit Registry and restart you computer.

5. This is the fix that did it for me.
