I am a tech managing a windows 2000 network on which most of the client machines have XP operating system running. This morning most computers developed a problem that caused a dialogue box to come up giving you 58 secs to close your applications before it shut the computer down. I went to the server and noticed that the RPC service has been stopped. When I brought it back up and restarted the service on the client machines, everything worked for about 5 minutes then the RPC service on the server would stop again. I spoke to a friend who is connected to Adelphia Cable, which is totally unrelated to my network and he has the same problem. Any ideas?
