    I have an NT domain with 1 DC and another newly created
    Windows 2003 domain with 1 DC. The same user/group
    accounts have been created on the new DC. NT DC has a
    shared network application being used by users. I need to
    join NT DC into Windows 2003 domain as a member server.
    And then configure all users to join the new domain. Can I
    just demote NT DC to a standalone server and then join
    Windows 2003 domain? Thanks.

  2. You cannot demote NT4 DC's like you can with Win2k/2k3. The only supported
    option is to reinstall the DC and then choose Member Server during install.
    You might want to look at a 3rd part product called Upromote as it can
    demote this NT4 DC for you but it is not free.

  3. I have heard good things about Upromote but never personally used it. You
    could do the Trust thing as needed.

  4. Hi Ian,

    Will you keep the two domains? As for your scenario, I would like to
    suggest that you try ADMT tool to migrate the users and computers from
    WinNT domain to Windows 2003 domain. So you can remove the WinNT domain and
    only left one domain.

    As for the NT PDC, you can reinstall it or use Upromote to demote it to be
    member server then join the new Windows 2003 domain.

    Here are some documents that may be helpful.
