NT4 to 2k : domain name

Discussion in 'Server Migration' started by julien Touche, Jul 24, 2004.

  1. i have a small question to be sure to avoid any conflict during my

    my initial setup was a Win NT4 server as PDC and file server and a Win2k
    file server (AD to be). All are in domain "old_domain".
    i also have a NT4 BDC, i sync, took off from network, promote as PDC and
    update to 2000 with a new AD tree named "company.local" but on the other
    part domain has stayed in the same domain than NT4 server (aka
    "old_domain"; seen on logon).

    so i'm not sure if i can connect without any conflicts my new AD server
    to network to make last part of migration. (promote the other server as
    AD+dns and sync with the tempory AD server)

    some comments ?

  2. Hi Julien,

    Thanks for your posting here.

    It will cause conflict if you put the new Windows 2000 AD to the original
    network. Because the NetBIOS domain name of are same and NT PDC does not
    work properly in the Windows 2000 AD.

    I would like to suggest that you try the following upgrade steps:

    1) Make a full back up for the current Windows NT domain.
    2) Install Windows NT 4.0 BDC on the sever.
    3) Promote the BDC to PDC. (Then the original PDC will be demoted to be a
    BDC automatically.)
    4) Make the new PDC and other BDCs online, and offline another BDC for
    recovery purposes.
    5) Upgrade the new PDC to Windows 2000 domain controller and install AD.

    I have included some documents for your conference.
