    I have a NT domain with a 2003 server as a member server. Due to hardware
    constraints, I cannot upgrade my PDC to 2003. I do have a machine that I
    can install NT, promote to a PDC, and then upgrade that to 2003. My
    question is, after I have Active Directory setup on the new 2003 machine,
    can I promot the 2003 member server to a domain controller, and remove the
    machine that I upgraded?

    Thanks for any input.

  2. Hi Mike,

    Yes, if you have a spare machine kicking around that will run 2003, you can
    install NT4.0 on it as BDC, promote to PDC, in-place upgrade 2003, run
    DCPromo on your 2003 member server and make it DC.

    Also consider the use of NT4Emulator key if required (Article 284937) prior
    to doing the in-place upgrade on temporary box.

    I'd run DCPromo on the temporary box and make it a member server. I *think*
    when you do this if there is an exisiting 2003 DC online, it will
    automatically transfer FSMO roles to it, but not 100% certain.

  3. Hi Mike,

    Thanks for your posting here and thanks for TheSingingCat's reply.

    You can promote another Windows 2003 DC after you upgrade the PDC to
    Windows 2003. It is recommended that you demote the original DC before
    remove it from network.

    The FSMO roles will not be transferred to other DC automatically. Please
    move all the FSMO roles to the new DC manually.
