    We have two domains that were created at different times. We have and was created first and
    is in its own forest. was created down the road in its own
    forest. Both are win 2003 domains.

    How do we go about creating a trust between the two domains so that an
    administrator terminal on will be able to access the
    Exchange Adminstration on domain?

    Start over and create a new namespace for one of the domains.

    Forest trusts will not allow domains in different forests to share a UPN
    I.E., if you have two forests that both have the namespace,
    Active Directory will prevent routing of the namespace, and
    there's no way to turn that back on.

    I don't know if NTLM/External trusts behave the same way, but the bottom
    line is that you've done a very, very bad thing.

    This is a real world situation not some test lab where you can just start over.

    First of all we dont have time nor the resources to start over, second of
    all I am dealing the hand I have been dealt with-- I didnt set up the
    original domains.

    So I didnt do a very very bad thing. I am looking for the best way to work
    with the scenario that is presented to me.
