Here you'll have a list of windows services:
http://www.blackviper.com/WIN2K/servicecfg.htmRemote Procedure Call (RPC)This service is rather vital. Practically everything depends on this service to be running. This is also the only service that you should not (and will not) disable via the Services MMC. If you do, your computer may (will) become unbootable AND you cannot place this service back to automatic to fix it. Leave it on Automatic and do not change it. If, for whatever reason, the service became disabled and you can no longer boot your system, please read the information here for a way to fix it.
Recent virus activity has prompted me to post additional information regarding Remote Procedure Call and automatic shutdowns. Please ensure you read all the information I have available to ensure you are not affected by this latest internet threat.
