    I have a 2000 domain consisting of 1 DC that I need to upgrade to 2003 and
    have it fall under my current 2003 forest. This site is connected via T1 to
    the other locations. Currently I am unable to create even a trust
    relationship between the 2000 and 2003. Connectivity is good as I am able to
    use VNC to directly connect however. I tried out the Active Directory
    Migration Tools however I was unable to connect to both domains at the same
    time. What would be the best route to do this?

    In order to successfully create trusts between external NT 5.x domains
    you'll need to be able to resolve the SRV records in the foreign domains.
    One nice and clean way of doing this is to hold a secondary copy of each
    opposite domain.

    domainA should hold a secondary copy of domainBs DNS zone; and vice versa.

    That's to start. With that done and the trusts created you can create a new
    domain in the existing forest and then migrate across using something like
    ADMT.

    yep, it's rather important to get your DNS zones setup correctly - on the
    2003 DCs you could also configure conditional forwarding for the DNS zone of
    your 2000 domain. But on the 2000 domain itself a secondary is likely your
    best bet.

    But try not to create another domain in the target forest - much better to
    migrate to an OU instead (the less domains you have in your forest, the
    easier it will be to manage).

    you can also use ADMT (or other tools) to migrate your exising AD
    domain/forest to that OU.
