    im going to move our single nt4 domain controller to
    windows 2003 server.

    My plan is this....

    install new server as bdc into domain

    do a manual synch of domain information via server manager

    upgrade bdc to pdc and then pull it off the network
    letting my users continue to work via the bdc.

    take the new pdc do a straight upgrade with the 2003 cd.

    ONce im in the AD and 2003 enviroment i want to pull the
    bdc out (old server) and just plop in the new 2003
    upgraded server. Will this work? i will want to change
    my ip address on my new server to that of my old server
    after the old server is offline so that my clients will
    point to the new server for the wins services that they
    were recieving from the old server. (otherwise ill have
    to change all client workstaitons ip address settings and
    thats alot of workstations).

    let me know any thoughts or ideas on this method.

  2. Hi,
    well, nice.
    ok (don't forget the Servicepack at least).
    Which you need to promote back to PDC, since they otherwise may not be able
    to login.
    This method may work, if you are lucky but I would see several concerns.

    Don't forget about DNS as the main name resolution method in Windows 2003 AD
    Domain and such small issues like that an disconnected NIC has some problems
    to remember the IP address while being disconnected. So you might need a
    separate switch to connect to for avoiding errors because off a non linked
    When do you plan to apply the security patches to the new server?
    What about the user data you may want to migrate (I assume stored on the
    current PDC), the printer settings and the profiles/fileshares? Sharenames,
    which the clients are aware, are surely pointing to the old server name.
    What will happen with workstations, which decide to change the password for
    the secure channel to the PDC during the migration time period (depending n
    your Client OS, of course)?
    Only a few dirty questions which would make me feel not to well with your
    idea of migration.
    Best greetings from Germany

  3. Hello,

    Thanks for your posting here.

    It is recommend that you keep a offline BDC as backup and upgrade NT PDC to
    Windows 2003 in domain.

    As for your clients, if you use dynamic IP address, you can assign the DNS
    and WINS to clients using DHCP.
