Error in Win2k pro SP4 and SP3

[SoKrATEs 0]

When I try to connect to the net with my dial up after a few minutes I get this error "svhost has generated errors and will close" then it closes the RPC service and I can´t download updates from microsoft or install any program (all need the RPC service). Don´t know why this error happens in a clean install of win2k pro and then updated to SP3 or SP4 (full SPs downloaded to my HDD, no express install) ;(

Thanks in Advance.

Solved is the Nachi virus (version of the blaster worm) Need some update and the antivirus install
