    Hi, I would like to get an advice on how to go about
    upgrading from NT4 domain to win 2003 server.
    here's what I have; One NT 4 domain with PDC and BDC,
    both host DNS on them plus
    the PDC have the file & printing function, The BDC has
    DNS/DHCP/Wins.

    I would like to do in Place upgrade but my PDC is out of
    disk space, but my BDC has the space for the upgrade.

    My question is this;
    - if I prompt my BDC and do the upgrade what happen to my
    DNS entry... do they get migrated into o the new AD??
    - would it be better to get a new box install NT4 BDC2 on
    it and upgrade that to win 2003
    - or can I set a new win 2003 server and move my DNS and
    DHCP/Win to it before I do the upgrade..if so How ??

    my other question is; if I get a new server and install
    NT4 BDC and than prompt it to PDC and upgraded to win 2003
    server DC1 (that way both my other BDC are still intact)
    what happen to my DNS and DHCP/Wins on my older BDC and my
    File/printing on Older PDC ( that got demoted to BDC) will
    be working and my end user accessing this ok under a new
    2003 server DC till I do the AD migration... or Not??

  2. Hi Nick,

    Thanks for your posting here.

    You can promote the BDC to PDC then upgrade to Windows Server 2003. After
    upgrade, the DNS/DHCP/WINS services will also be upgraded.

    It is recommended that you install another BDC, then perform synchronize in
    the domain. Then offline the new BDC for backup.

    Yes, you can also install the third BDC then promote it to PDC, and perform
    upgrade.

    You can move the DNS, DHCP and WINS to the new Windows 2003 server before
    upgrade. Here are some references:

    After you upgrade the new BDC to PDC, then Windows 2003 DC, you can install
    DNS service on this Windows 2003 DC and create AD-integrated Zone. You can
    change the DNS on NT to a secondary zone pointing to the new DC. It will
    not affect others service on the BDC.

    In addition, you can set the NT4Emulator registry on the Windows NT 4.0 PDC
    before it is upgraded to Windows 2003. Please refer to the following
    document for the detailed information.

  4. Hi Nick,

    As I know, there is no particular article for this scenario. You can try
    the FSMT to move the file shares. As for the user profile, you can also use
    robocopy with the "/SEC" switch to copy profiles to the target Windows 2003
    server with permissions.

    You can also try USMT tool to migrate user state (VALUEADD\MSFT\USMT from
    the Windows Server 2003 CD). For more information, please refer to the
    following web site.
