Migrating SID's to a domain of the same name

    Here is the dilemma. We have a completely new system to setup as a domain
    and want to keep the domain name the same.so we setup the new server in the
    lab with the same name. I have scripts to backup and migrate the users and
    computers but the Sid won't come over.

    When I try to put an old machine on the network I get an event on the server


    The computer name <name> connected to server \\<server name> using the trust
    relationship to the <domain name> domain. However, the computer doesn't
    properly know the security identifier (SID) for the domain. Reestablish the
    trust relationship.


    I want to migrate the users but since they are the same name I cant have
    both systems on the network at the same time. The ADMT requires a trust
    between the domains and I cant do that with this current setup. Is there any
    other way to migrate the SID's ?

    Sure I can rejoin it to the domain but I have about 400 machine to do.

    Thanks in advance

  2. Hi John,

    Thanks for your posting here.

    Although the domain name is same, but the domain's SID is different.

    As for your scenairo, in general, we can perform In-Place Upgrade. For
    example, if your source domain is WinNT domain, you can upgrade PDC to
    Windows 2003 domain. Here are the steps.

    1. Perform a full backup for the existing Windows NT PDC.
    2. Install Windows NT 4.0 BDC on the a new server and apply the latest
    Service Pack.
    3. In Server Manager, promote the BDC to PDC.
    4. In-place upgrade the new server to Windows Server 2003.
