Exchange / Trust Issue

This is also posted in the Exchange forum. Don't know excatly who best to
ask on this, networking / windows people, or exchange...so hopefully,
everyone will answer :-)

Good evening, all. I'm looking for anyone that might be able to shed
somelight on a wacky problem we're having.

I have an NT4 domain with a Windows 2000 member server running Exchange 5.5
Service pack 4.

Before I started at this job, a Windows 2003 Domain (Forest in Native Mode)
was setup, and has accounts that for the most part duplicate the NT4 domain,
user names and passwords do no always match between domains.

There are no trusts between the NT4 and 2003 domain. What I'd like to do,
is get trusts established, so that users are not prompted for login - and
also, make the 1st steps toward Exchange2003. All of the servers at this
site, with the Exchange server (only 1 exchange server) are pointed to the
Same WINS server.

Here's the problem. As soon as the trust is established (NT4 truts 2003)
some users can no longer log into email. This is before I change the
Primary NT account, or do anything else. Users can no longer use Outlook or
OWA. The problem seems to reliably show up on Windows 98 clients, but what
could that have to do w/ a loss of Access in OWA? To make it worse, there
seems to be no rhyme or reason for who has the problem. A few users have it
consistantly, but one time we establish the trust, my own account
experiences problems, and the next time no access. Chaning the user's
primary account from NT to 2003 domain has no affect on them being able to
access.

Oh, when we try OWA we use nt4dom\username or cmh\username so we're sure
which account is being validated. If we use an incorrect password for an
account, we get prompted again. if we use the correct password, we get
right to a 'OWA unable to get your mailbox' error. This is amazingly
frustrating.

Does anyone have any idea what might be causing the problem?

Thanks in advance.

This should help. In order for OWA to work there are some user rights that
need to be assigned. Check out the following article.
