OWA Pass-thru authentication not working on one system on the lan   

All of my lan users can hit OWA (stand alone ex2003, latest sp)
internally and it doesn't prompt for credentials, it just opens their
mailbox as expected. I have one system that always get prompted. The
internal OWA URL has been added to the trusted zone and I can open
files shares on this server without being prompted. The system in
question is in the same subnet as all the other systems and there's
nothing in IIS authentication options singling this system out from
the rest. Oh the system doesn't have the firewall turned on or
anything like that. I've tried a new test user so as to get a fresh
profile, no luck. I've also tried the same with an admin account and
also had no success. As a side note, this is their first and only
exchange server and is a new install of both OS and exchange. Nothing
has been changed from the intiial settings.

What would cause something like this? Is this RPC related? If so, how
might one go about fixing it? Thanks.

arg sorry, I just noticed this is the ex2000 group. I'll repost
elsewhere, though if anyone has any advice I would still appreciate
it.
