100% CPU usage in System process thread

I run a Windows 2000 Server standard w/ the latest system packs and
hotfix KB889081 (http://support.microsoft.com/?kbid=889081) installed
(which didn't solve my problem!). My system continuously runs at (or
near, if not at) 100% in the System process (not the System Idle
process). This has only been going on for about three weeks or so
(apparently after applying hotfixes which came out on Feb 11, 2005 and
after, there was an error when installing KB886906 which occurred daily
(automatic updates) until I installed the update manually on March 8,
2005). However, I can't prove this for sure because I didn't start
actively monitoring the CPU thread (with an event tracker) last week.

I've searched all over the web for information about this problem, but I
can't find anything. I've tried everything that I can think of,
including the special hotfix listed above (KB889081 - 100% terminal
services problem - which didn't work). Can anyone help? I have no idea
what to do next.

Is there any other information that would be helpful to you in looking
at the problem? Just post about it and I'll get you the information.

I tried to attach the full cpu thread information from pstat but I can't
get a post with an attachment to stick on the newsgroup. However, in
general after only 32 mins of uptime the System process has used about
10 total minutes of CPU in various threads and it just goes up and up
from there. Here's an excerpt:

I ran an adware scan on Saturday afternoon and didn't find anything.
Spybot, adware, a squared, etc. I also scanned for viruses, again, using
Norton Corp. and the latest McAfee stinger as suggested in some
responses in win2000.general (see my post there too if you like).
However, there was no effect. Can anyone help? I'll be happy to post any
other information you need.

Here are some updated pstat results (and zip file updated, see below). I
still don't know what to do about this problem... help?
