win NT domain controller - PDC, BDC and standalone...?

    Hello All,

    I am about to install a temporary NT server to use it in a process of
    upgrading to 2003 std.

    I just installed one machine, and I have chosen that the machine should be a
    PDC.

    But my question is: can I later change the domain, or even demote the PDC to
    a standalone server (workgroup)?

    Can I switch between PDC, BDC and standalone (workgroup) several times,
    without re-installing the server?

    Thanx in advance,
    Kizetoni, Denmark

  2. Hi,

    On Windows NT 4.0 you can change between PDC and BDC but not to any other
    role (e.g. member server or standalone) out of the box.
    On Windows 2003 you can do that -- you can make server member of domain,
    promote it to domain controller and later demote it to member server or even
    stand alone server.

    For Windows NT 4.0 there are some 3rd party tools that are supposed to be
    able to transfer PDC or BDC to member server -- but I never tried them.

    Personally I use Virtual PC or something similar when I need to change roles
    and configuration often. It speeds up the process...

    Hej Mike,

    thanx for your quick answer (again :eek:)

    Now that it is you again answering - it is the case related to my previous
    question (upgrading an existing domain from NT to 2003 with help of a
    "temporary" machine).

    The sister company is physically on the other location, I wouldn't like to
    have to go there to install that temporary NT server - just to be able to
    make it a member of the domain.

    But now after that you said (I don't want to begin to fiddle with 3rd partys
    progs), it seems that I don't have other option but to go there and make the
    temporary machine a BDC already during the installation...? But that means I
    should spend hours there installing, and I don't have time for that.

    Couldn't I make an installation this way:
    1.) install win NT on the temporary server, and when asked to choose a role
    for the new server, I choose PDC (since if I choose BDC I would be asked to
    connect to PDC? and since if I choose standalone, I wouldn't be able to make
    it neither PDC nor BDC again?)
    2.) I make the whole installation process through, and update, and all
    things, included IP and those practical things
    3.) bring the new server to the original NT PDC's LAN and then make it
    member of that original domain (now, here is my question: how will the
    original NT PDC react when this temporary NT PDC comes into the domain, and
    claims that IT IS a PDC? this is crucial, since I intend to make this
    temporary NT server a BDC in the original domain)

    Afterwards can I start fiddling with PDC/BDC and upgrading to 2003, as you
    described in your previous e-mails...

    Does this sound like a possible solution?

    thanx in advance, Kizetoni

    You can't "join" a domain as a PDC. Selecting a PDC creates a new domain.

    To join a domain as a BDC or member server, your computer needs to be able
    to establish a windows networking connection with domain controllers on that
    domain.

    Hello Robert, thanx for the input!

    But I noticed that I can change the domain on a PDC - doesn't that mean that
    I could change the domain name to one that already exists, and then bring
    this new PDC to the original PDC network, and then when the conflict
    begins - simply choose one of the machines to be a PDC and other to be a
    BDC...?

    I found out a solution! :eek:)

    First, during the installation I make this new server a BDC to our local NT
    domain.

    Then I can change the domain on this BDC to the new domain at the new
    location. (first I create a computer account in that new domain)

    After restart I complains that it couldn't authenticate, and that logon
    service was stopped. But in the server administrator I can promote that one
    to PDC, and after restart everything works fine!

    I have been "walking" the machine through several domans as PDC and BDC, no
    problems!

    I thing that the Administrator account must have the same name, and
    password.

    Regards, Zoran

    Right. Now try leaving it in one of those domains that you've "walked" it
    through, for a week or two, and then see if you still don't have any
    problems.

    OK, thx, then I guess I will have to drive up to them, and do the installing
    while the PDC is present..

    Thx!

    ..
    Thats what I'd do. I know its annoying, but not as annoying as it would be
    later if you didn't do things "properly".
