Help with Windows XP shutdown error

[Arty]

Hello, I'm trying to help a friend with Win XP through a
problem. When he turns his pc on it stays powered up but
then he gets an error message saying "The system is
shutting down. Please save all work in progress and
logoff. The shutdown was initiated by the Win NT
authtority system. Windows must now restart because the
RPC terminated unexpectedly." After that the pc reboots
automatically. Any ideas on how to fix.
