2 DCs in 2 domains (only want 1 domain with both DCs)

    How can this be? Both are GCs for mydomain.com. When I open up AD Users
    and Computer in the new DC for mydomain.com, it's a clean AD (none of my OUs
    or users or the old DC) and when I open up AD Users and Computers in the old
    DC for mydomain.com, it shows all the OUs and users but doesn't show the new
    DC in the domain computers container.

    I want to rep the objects from the old DC to the new DC but can't because
    the they don't see one another.

    I obviously don't know what I'm doing! Can anyone help?

  2. If both the DCs are in the same site see
    as a starting point.

    You chose the wrong options during dcpromo. You should run dcpromo again on
    the new server (the one that does not have any users or OUs that you created)
    to remove active directory. Once it has been removed, run dcpromo again and
    choose to install the domain controller in an existing domain.

    Thanks, I just tried that and demoted it and now get the following error
    trying to dcpromo again in existing domain after entering the account:

    The following error occurred when DNS was queried for the service location
    (SRV) resource record used to locate a domain controller for domain

    The error was: "DNS name does not exist."
    (error code 0x0000232B RCODE_NAME_ERROR)

    The query was for the SRV record for _ldap._tcp.dc._msdcs.datasculpting.com

    Common causes of this error include the following:

    - The DNS SRV records required to locate a domain controller for the domain
    are not registered in DNS. These records are registered with a DNS server
    automatically when a domain controller is added to a domain. They are
    updated by the domain controller at set intervals. This computer is
    configured to use DNS servers with following IP addresses:


    - One or more of the following zones do not include delegation to its child

    .. (the root zone)

    How do I register these records? Thanks.

    Is the new DC pointing to the old DC for DNS? If so, then I would run
    netdiag /fix on the old DC. Netdiag will try to reregister any DNS entries
    that are missing.

  6. If, after running netdiag you still have this issue, ensure that the
    soon-to-be DC is pointing to the original DC for DNS. It needs to resolve
    the DNS query you posted. That is held on the original DC (if the DC is a
    DNS server).
