    I have SBS (the old version with Windows NT2000).

    I need to add a WXP client computer to a new domain due to a migration
    process. However, I need the local administrator password of this particular
    and I don't have it.

    The question is: If I log into the XP computer as a domain administrator, it
    doesn't let me to change/reset the local administrator password (it says
    that I don't have permisions to do that but I should !)

    I have tried in other computer of the same network and I can do it with out
    any problem.

    What can I do ???

    Thanks a lot,

  2. If you can logon as the domain admin you should be able to join the XP Pro
    machine as such. Have you tried that?

    Hello Dirk,

    Yes, I have tried. from the server I try to add the computer and it says
    that I don't have permision, and as I said, If I log with domain
    administrator into that computer, I can not change the local administrator
    password neither removing the computer from the current domain to join the
    new one.

    Any idea ?

    Thanks a lot,

  4. I meant, you said you could logo into the local XP Pro machine as the domain
    administrator. If so try joining the domain from the said XP Pro machine. It
    will ask for the Domain administrator name and password.

    Thanks Dirk. We will try it today in our customer. I hope it works.

    However, do you now why we can't change the local password administrator
    when logged as a domain administrator in that PC ?

    Thanks a lot,

    Definetly, we can not do that. When we log in that XP as a domain
    administrator, the posibilities of removing/adding the computer to a domain,
    are disabled !!

    Any idea ?

  7. This is an XP Pro NOT XP Home machine?

  8. Hi there

    In order to join a computer to a domain the user that is logged on to the
    computer must have local administrative rights. So you are right, you do
    need the local administrator password, or the username and password of a
    local administrative account.
    If you don't have the password you are only left with 2 options:
    1.) Re-Install Windows and remeber the local adminstrator password
    2.) Find a "Password crack" utility. they are out there, but for security
    reasons I rather not get involved or post a link.

    Have Fun

    Yes. This is an XP Pro.

    I don't think is true what it says Peter Schüler. In other computers in the
    network, I have done it with out any problem. There is something wrong with
    this particular computer but I don't know what it is.

    Any other idea ?

  10. To confirm, you can't logon to the XP Pro machine as the domain
    administrator then go to control panel, administrative tools, computer
    management, expand local users and groups, click users, rt pane, rt click
    Administrator, click set password and ignore the warning doing so?

    Hello Dirk,

    When we do that (logging as a domain administrator), when we set the new
    password for the local administrator, we get an "Access denied".

    Any idea ?

  12. Hmm, not sure but may be some group policy locally that's hashed. Bottom
    line without the local admin password you may have a problem now. Have you
    tried no password, blank? Any chance the last IT or user knows it? The time
    lost and effort at this point would lead me to have flattened the machine
    and clean installed XP Pro...... (Documenting the local Administrator
    Password this time of course"

    Their are some password recovery software apps out there but I have never
    used them and as such am not familiar with them. Maybe someone else can
    recommend a different scenario.

    Sorry :(

  13. Dirk,
    When a computer is joined to a domain, the Domain Admins group is entered
    into the Administrators group on the local machine. This group can be
    removed, and that sounds like what has happened here.
    If you know the password of another user with admin rights, you can log
    onto the local machine and add the domain admins back to the local admin
    If this isn't possible, a reinstall is in your future unfortunately.
    Thanks and good luck!
