Getting Event 4609 & Horribly Slow performance

[Mike Howard]

I am trying to figure out what happened to an XP Home
system that is running extremely slowly. After 20
minutes, the system is booted enough to let me start task
manager (5 more minutes) and and see that there is no
unusual drain on performance. The CPU time seems to go
from starting services to idles, etc. The CPU
utilization is 100%. It seems like something hidden is
sucking up the time. The event log shows events 4609 and
8193 happening. I read and followed KB article 823772,
but the problem persists. The swap space is fine and NAV
didn't find anything using their 11/10 virus definitions.
The last time the system ran well, it booted up fine, but
started to slow done after booting. It has the same
problem to a lesser degree in safe mode. Same mode is
very slow in the DOS box and screen repaints. The task
manager show 100% CPU utilization in safe mode too.
The system is an Athlon XP2600, 1G RAM, so it is not
normally a dog in performance.

Any Ideas?

Thanks,
Mike Howard

What changed between the time things worked and the time they didn't? If
the system is clean (and it certainly is powerful enough to handle
indexing and other apps running in the background), then check out the
hardware. Is the power supply sufficient? Is the system overheating? Is
the RAM good? Check the hard drives and cables. Strip it down to the
motherboard and video card. Run it with the absolute minimum of
services and programs. Do your troubleshooting one step at a time! Post
back if you need more help with details about what you've done.
