Vista RPC Server not available

I have a laptop over here with windows vista that someone gave me because it wouldn't connect to the internet. After some serious malware removal its back online however alot of times doing other things I get RPC Server not available and I cannot get to control panel or if I right click on computer and select properties or manage.

The RPC service is present and running but for some reason it thinks it is not. Please help.

 

Another person solved their's this way:

The RPC server is unavailable because the service couldn't function properly because it's dependancy (server service) couldn't start... I checked the dependencies through the server's properties and I looked through services and started those required dependancies to start the server service, once that started... Everything functioned properly.

You might also want to check all the services against BlackViper's list to be sure everything is at the proper setting.
