Making a server on one domain the domain controller of a new domain

Discussion in 'MCSA' started by Limited Wisdom, Sep 10, 2006.

  1. Ok, so I'm stepping through the Windows Server 2003 Environment
    Training Kit for the 70-290 exam. Obviously, one of the first steps is
    setting up a Domain Controller. Rather than building a server from
    scratch, I figured I would use one of the staging servers that we have
    on hand and just skip the base operating system installation steps and
    jump right to the install of the Domain Controller piece.

    The server was running Windows Server 2003 Standard R2 and belonged to
    another domain.

    The first part of the install completed successfully, it asked me to
    make it it's own DNS server, which I did. Then it asked for a reboot. I
    rebooted the machine and was then prompted to login (obviously). I
    don't know what to use to login. So now I'm stuck.

    The "log in to" box has one option - contoso (the domain the training
    kit had me set up). The local machine name is not listed (did that get
    blown away in the domain creation process?), literally, nothing but
    CONTOSO. So I tried "Administrator" and the password that used to work
    (when it belonged to our primary domain). I tried no password. I'm at a

    I know I could rebuild the machine from scratch but it has a few files
    I'd like to keep on it. No biggie if I just can't, but it's also kind
    of a matter of principle, you know? I'd like to be able to fix the

    It's also probably worth noting that the machine is in the office and
    I'm sitting on my recliner at home. I'm using Remote Administrator to
    gain console access to the machine. Of course, I'll be back in the
    office FAR too soon :).

    Thanks in advance.

    Hi Limited,

    Good You cannot log on locally to a domain controller, which means
    that the dcpromo worked. If this is the first DC in the forest then the
    username will be Administrator, and the password would be the one you
    supplied during the setup process.

    If you do not remember that then there are a couple of utilities out there
    that could recover it, but frankly if this is a test machine with nothing on
    it it will take less time and money to simply start from scratch.

    Good luck!

  3. If you don't remember the password, you can use this utility to reset/change

    You might find it useful to instead download the Ultimate Boot CD which has
    this utility and DOZENS more. (All of this is free by the way). Check out
    UBCD at

    Good luck,

    Hi Jonathan,

    Actually the reason I did not suggest either of those utilities is because
    if I am not mistaken they only work for local user accounts, which a domain
    controller does not have. Please correct me if I am wrong!

  5. Thanks so much for the reply.

    Was there really a point where I specified a password? How embarrassing
    - I can't remember doing that AT ALL (Does this mean I'm officially

    FWIW, I tried using the two passwords I might have used and neither
    worked - I can't believe it. Did I really set a password?

    I'll believe you. Tomorrow I'll try a password reset utility I have -
    just ticked that I'm stumped over something so stupid as not paying
    attention during setup - but I really don't remember setting a

    Thanks - I'll let you know the final resolution.

  6. Ahh yes, sorry -- you are correct. I have never had occassion to use it on
    a DC. Relevant info below:

    I tried it on Win2k PDC (Active Directory), and it didn't change the
    a.. ActiveDirectory (AD) is a completely different database.
    b.. There is no support for directly changing passwords in AD.
    c.. To clear things up: The Active Directory SERVER itself is not directly
    supported, but workstations (w2kprof) and servers (w2k server) that is just
    MEMBERS of the domain can have their LOCAL passwords changed by the utility.
    d.. But..
    e.. John Simpson has made instructions on how to reset that pesky lost
    administrator password in AD.
    f.. Many thanks goes to John for this!
    g.. And I may as well in a future relase make a frontend for the
    screensaver trick he uses, so it will be even easier.

    Use Firefox instead...

  7. Jonathan, you crack me up!

    I didn't attempt to use a password reset utility, but I did just
    reinstall the OS. Turns out, the files I needed were on a separate
    drive - so I figured that would be the easiest solution.

    Anyway, I was never prompted for a password during the install, but I
    noticed that it said (in the very last dialog box) Domain Administrator
    password will be the same as the Administrator password.

    Thanks all for the help (and the useful link - that's one to keep in
    your back pocket).
