    We currenlty have a 7 year old NT 4 Server as our PDC. We are purchacing a
    new dell 2580 PowerEdge server to replace it. We ordered it with 2003
    Enterprise server with 50 client cals.

    It looks like the proces to migrate from nt4 domain controller to 2003 on
    new hardware is quite involved. In the old days I just brought the new
    server up as BDC, synched up, demoted the old server and promoted the new
    server. I believe in this case I would have to upgrade the old server to
    2003 AD structure first. This makes me nervous as the hardware is old and
    the hard drive is full.

    So.... We only have about 50 users, 4 file servers (that I am moving to 2
    NAS devices anyway), and a dozen shared printers. I was thinking that I
    could just bring in the new server as a new domain, create the tree, and
    migrate users over one by one. If we do this, we would need to alow users
    logging on to the old domain to acces objects in the new tree. Is there a
    way to "trust" the old NT domain.

    Another consideration is that our company is purchasing another company in
    another state. They currently have an AD tree. In about 6 - 9 months will I
    be able to have the two trees "trust" each other?

    do you have another NT4 BDC in your domain? if so I would take BDC offline,
    then upgrade PDC to 2003 DC, if something goes wrong you still have NT4 BDC
    box, if upgrade goes well then run dcpromo on your new 2003 and move over all
    FSMO.. this is easy and reasonable way of doing it. I would avoid the other
    scenario with creating new domain and trust relationship... but this just my

    It is better idea to build new tree and move users and other objects by using
    active directory migration tool.

    working on existing PDC may create Hardware issue.
