A 2k3 server locks up. Completely, read again Completely. No response from the machine (video, keyboard, mouse). I have to use the reset button. After the reboot it is fine for another 12 to 24+ hours. The system does not log anything wrong, except for the unexpected reboot. There is no warning, it happens suddenly. Heat is not an issue. I can't find what is going on. Should I log performance counters? which ones?

the ones that monitor system resources. set up the monitor but also manually look at them thruout the 12-24 hour cycle, see if they are diminishing over time...did this used to work fine? what changed? new service pack? look at the pc carefully when booting. is it reporting all the RAM you expect? what applications are running? anything new? any upgrades to anti-virus?...do you have a firewall

How long has it done this? A week+ or so?

What I am saying is, is this machine patched for the RPC/DCOM vulnerability that the Blaster worm is exploiting?

Maybe a Blaster worm tried to infect it, and was not fully successful. When this happens, the RPC service gets mangled. On some systems, they go into the 60 second reboot cycle. On others, RPC shuts down, which really screws up a lot of other Windows functionality.

Anyway, have you patched this server and done a full anti-virus scan on it?

Good luck
