Windows 2000 Server - Myst. Crash

[runboy]

I have a Win 2000 Server (Webserver IIS5.0) sitting at a remote location. It has been running fine for 5 months and now all of a sudden it crashes average 1 time/week.

It is not overloaded at all. It recieves 600.000 hits/day. and the weblogs don't show anything suspect up to the crash.
I am monitoring the following counters in Performance Monitor:

Memory\%Committed Bytes In Use
Memory\Pages/sec
Paging File(\??\Dagefile.sys)\%Usage
Paging File(\??\Eagefile.sys)\%Usage
PhysicalDisk(_Total)\Disk Time
PhysicalDisk(_Total)\Disk Bytes/sec
Processor(_Total)\%Processor Time

Any good suggestions to new counters to try ;o) I have currently expanded the log with some networks counters.
All of them were normal at the time of the crashes. 5-10% CPU power etc.
No memorydump and no nothing.
I thought that it may be the powersupply, but if that had a hickup I guess the server would just restart. Temperature/cooling is not an issue.

Server:
Dual PIII 800 MHz (Tiger 133 MB)
1 GB RAM
1 x 9.1 GB SCSI ULTRA 2 LVD, 5.2ms, 10,036RPM, 2MB
1 x 18 GB SCSI ULTRA 2 LVD, 5.2ms, 10,036RPM, 2MB


Hope somebody has a good idea.

Do have a UPS on this server, riiiight?

If not, get one. Same damned thing happened to me. Turned out that whenever I turned on my air compressor in the workshop, it glitched the power and drove it bonkers. Now everytime I do it, my UPS ker-chunks.

Yes, I do have a UPS unit on it, but even a power surge would normally reboot the server. My server just gets "stuck"
