Could anyone give me any possible reasons on why the system process is
consuming all CPU resoures on one of our Windows 2000 server?

Details of the system: P3-1.266MHz, 3GB RAM, is a DNS server (out of 2), is
a DHCP server (out of 2), home directories stored on it, usually 150-200
users logged at a time.

Processor runs at 80 – 100% during main logon times (150-200 users), and it
varies from 2%- 90% during times when only a couple of users (5-10) are
logged on.

I have seen this happen on a workstation when Symantec Antivirus freaks
out. See if temporarily disabling your antivirus helps at all.

HTH,

I had something similar happen on my desktop. One single process was taking
all available cpu resources. I had just built the system, went to work for
two hours and came home. My wife managed to plug in the dial-up, setup IE
and went surfing. Within 10 min she downloaded a virus. Turned out it was a
trojan virus. Granted there may be other possibilities but I would get the
latest virus definitions and run a scan of my files.
