I had a problem where XP SP2 started taking about 2 minutes to logon to
a domain; regardless of the user account. Also didn't seem to matter
if I used a wired OR wireless connection. I searched all over the web
and through the newsgroups trying all sorts of suggestions and fixes
with no luck. After 2 days of searching, I narrowed the problem down
to a hotfix. I'm 99% sure it was KB920342. (I also uninstalled
KB885894, but I don't think that was it.) I thought I'd post this just
incase it helps someone else.
