At 9 am every day our Server 2000 machine grinds to a halt.  Started about a month ago.  The slow down last about 30 - 45 minutes.

Process explorer doesn't revial anything.

Task manager shows that 'System' is CPU usage is high... 95 - 100%

I would drill down using performance monitor. It can give you more specific details.

See the help and check anything suspicious.

Anything in the event logs ?

Since 9am is when a lot of users may be logging in, it could be something related to that.

ANy login scripts running ?

Anything else running, ANtivirus etc ?

I hope this helps !

I checked the logs, etc.  Nothing appears to be running.

I'm not familiar with a drill down method in a performance monitor...  can you elaborate?

Monitor this counters to get a genereal picture on what's happening on your server.

Disk: (Phyiscal disk)
Avg. Disk sec/Transfer
* Must be lower than 25ms

Memory:
Available Bytes
* Should be no lower than 20-25 of installed memory.
Page reads/sec
Page writes/sec
* Combine these 2 values. Should not be higher than 150i/o /sec / disk. Lower the better

Processor:
% Processor time
* Less than 70-80%
% Processor time(N)
* N = one CPU if you have multiple cpus. Also less than 70-80% per CPU

Network:
Network interface
Bytes total / sec.

These are suggestions for a general picture on what's happening on the server. It helps to find potential bottlenecks.
Further more detailed monitoring is needed if a value exceeds the recommendation.

Taken from: Tuning IBM @server xSeries Servers for Performance:

These links will help you pinpoint any bottlenecks and tell you what you can do about it.

Goodluck.
