    looking to take an exisiting nt4 domain controller and migrate the user accounts to a sbs2003 pdc - then leave the nt4 server up in working condition (joined to new domain)

    what is the easiest path for this ?

    it looks like i can use the admt2 tool to transfer the userid/account info from the old domain to the new. At that point can i dcpromo the nt4 server- reduce it back to a non-pdc.. then join it to the new sbs domain?

    after all of this can i rename the new sbs domain to the old(er) actual domain name?

    also.. i have already (mistakenly) dcpromo'd the sbs2003 server to join it to the current domain.. got all kinds of errors and promo'd it back to being its own active directory pdc. (giving it a different domain name then the original).. do i need to start from scratch.. or will it live a happy life as is ?

    thanks much.

  2. You can't DCPromo an NT4 box. You can't switch between PDC/BDC or member
    server. You option would be ADMT the account to the new box, then format
    the NT4 and reinstall it as member server (Not a BDC as it is not allowed
    in SBS2003)

    hm.. thanks ray.

    sticky situation is that i believe there are crucial apps on the nt4 box
    which ionly work on nt4.. 'd like to not take down (ie.. re-install)..
    guess i'm not up on my nt4 skills. so you are saying there is no way of
    de-moting an nt4 box from a pdc back to a workstation (other than
    format/reinstall nt4)

    quite a pickle..

    thanks for the advice.

    (non-pdc) to be joined in the sbs2003 domain ? correct ?

    thanks again.

  5. Unlike Win200x, NT4 can't be switch between PDC/BDC and member server. To
    change the role, format reinstall is the only way.

    You can add NT4 member server to the SBS2003 domain, but NT4 PDC/BDC won't
    work as the domain is setup in Windows 2000 native mode (which accept
    Win2k/2k3 "DC" only)

    If you really want SBS2003, you don't have any options except rebuild the
    NT4 box.

    Thanks very much Ray. You've saved me much wasted time.

    When i re-create a fresh nt4 install and join it to the new 2003 domain will
    I need to install the active directory client software on the nt4 box ?

    thanks much!

    Another alternative is not to use SBS 2003, just use 2003
    Standard edition. Then you can add the 2003 server to your
    current NT domain. You may not get all the functionality
    out of the 2003 server, but at least you will have your
    old apps working correctly.

    very true- part of the fun is that the sbs2003 is already purchased and
    installed :)

    should i be able to rename the sbs domain after I migrate the nt4 domain
    groups/users/setting over to it without trouble ? or will w2k3 get upset ?

    thanks.

  10. Can't rename the server or the domain after the SBS installation. Not
    supported.

    sorry ray.. lack of sleep has me not leaving enough detail.

    i was speaking about the sbs 2003. i have dcpromo'd it back and forth
    several times now since I've first installed it from its original domain name
    to a standalone-- back to a different domain name..etc.
    to this point i have not seen any ill effects.

    it would save myself (and my client) several hours of work if I did not have
    to re-load sbs2003 just for this point .
    thanks.

    It depends what these are, and how you access them on the server..

    If you follow the Microsoft SBS_MigratingSBS45 document, when you use
    ADMT you set up some legacy links:

    Net Localgroup "Pre-Windows 2000 Compatible Access" Everyone /Add
    Net Localgroup "Pre-Windows 2000 Compatible Access" "Anonymous Logon"
    /Add

    You should already have both servers on the same subnet but with
    different domain names. At this point, you should have access to the NT4
    server's files from workstations attached to the new SBS domain.
    Depending on what your apps are, they may well work.

    This is not a situation you'd want to run indefinitely, but there may be
    a cleaner permanent solution. There is no trust concept with SBS, but
    there may be workarounds, such as having the same user names and
    passwords on both servers, which allow you to continue with the NT4
    apps. There is certainly no problem with having an orphan NT4 PDC on the
    same subnet but different domain as an SBS. The only question is whether
    there are techniques to allow the SBS workstations to get what they need
    from the NT4 machine, which will depend on the apps e.g. are they true
    client/server or do they depend on users' file permissions?
