XP Rebooting System After 1 Minute Warning On Line

When going on line no matter which ISP or XP system (tried two) get Official looking Operating System message: NT Authority\System ....... Remote Procedure Call (RPC) Service Terminated Unexpectedly ...... Exit programs and logoff .... 60 second countdown starts immediately and cannot be stopped by Task Manager..... This started today on 2 machines when going on line and both these systems were just updated by Microsoft on line to update to DirectX 9.0b last week. HM-M-M-M ?????? Anyone else experiencing this cute little problem ???
BTW no problem going on line and downloading etc. with W98 (downloaded current NAV and no virus on either system)

Hoho, this is not a virus (wasnt in the begining, though there are worms already...), its just a bug in windows xp/2k. The reboot is just a "bonus", its happens when the attacker, who used the exploit quits from your computer. Windows is good, use it PPPP
Sorry, its just that, i dont understand... if ppl DO use OSs which famous of its insecurity and has the most bugs, why DONT the use firewalls? A simple firewall (even that shity one which integrated in xps) could save you from this happenings. The RPC exploit uses mostly the port 135.

Anyway, i think its good that this happened... ppl maybe wake up, and consider doing something about their safety (and not just runing to that stupid MS to download a patch when its already too late...)
