    Hello all -

    I have two offices... both have two servers running W2k Adv Server. Both
    servers in Office A has a brand new installation of W2k Adv Server w/ SP4.
    One of these servers is the PDC and the other is a member server. I am
    trying to configure a 2nd domain with two servers at office "b" and have
    that domain in the same forest as office "a." When I run the AD wizard on
    either server in office "b" [remotely from office "a" with Remote Desktop
    Connection over a VPN tunnel], I get the following error: "Active Directory
    Installation Failed."

    The error message continues to say, "The operation failed because 'The
    remote attempt at server to remove server CN=NTDS Settings,
    from the enterprise failed. The DSA object cannot be deleted."

    I tried researching this problem over the weekend and found an article
    saying my AD is corrupted with old objects and to do one of two things: (1)
    remove objects that shouldn't be there anymore or (2) install the OS again.
    I opted for #2... and I'm still getting the error. AD isn't the problem...
    any ideas of what the problem is?

  2. Hello Robert,

    On the existing domain, with one DC if i understand correct, please run dcdiag
    /v, netdiag /v and post the unedited output here.

    It sounds like that you had installed or tried to install another domain
    in the forest? Check with this articles for older DCs and old domains existing
    in the AD database:

    If they are listed in the AD database and do NOT exist, you can remove them
    according to the same articles. And keep in mind to have a good/tested backup
    available, in case something goes wrong.

    Best regards
