I did find this in the microsoft.public.windowsxp.perform NG:
"I was able to fix this problem on my computer
by disabling "Client Server for Netware" under
network setup properties."

Also found this in "".basics

Does it truly lock the OS permanently, or does it just take a REALLY long
time to come up? If it's just ridiculously slow, one thing to try would be
to update your video card drivers. It may just be having a difficult time
processing some of the effects used (or perhaps even causing a lock in the
driver itself, if it's very poorly written). Another consideration is that
some program will install themselves into your right-click menu, and they
may be causing a delay or locking up entirely. If you have an application
that does this (such as zip programs or virus scanners) you may want to try
disabling this functionality or uninstalling the app to determine if it's
the culprit. Unfortunately, there's no really easy answer here - it's going
to take some tinkering to discover what code is causing the freeze, because
it's not Windows code that's doing it.
