    Try going to a command prompt and typing:

    netdom /Domain:domain  /UserD:user /PasswordD:password /REBoot:20

    This will cause the computer to be removed from the domain using the user password specified and rebooting within 20sec.

    You must be a member of the local Administrators group.  By default, Domain Admins and the local Administrator account are all that are there when joined to the domain.

    Did you try logging into the machine as the local administrator
    Log in as local admin and add to a workgroup

    netdom.exe is found onthe win2k resource kit on your win2K installation cd under the \support\tools directory.  It is actually in the file.

    And yes you must be logged in with an account that is included in the local adminitrator's group.

    i think this might be a summary of the above.

    reboot the computer, login as a local administrator (this computer) account.
    then go to the network settings and just join a workgroup.

    this should leave the domain..

    for the access denied error, you could always try a different domain administrator account to leave the domain..

    When you installed the OS on that PC the first time, was it directly connected to a domain or was it first a local workgroup computer?

    Accepted Solution

    Login to the domain from another machine that has the Admin tools available. Open the Active directory and remove the machine manually. Then locally remove from the domain by placing it in a TEMP workgroup. A LOCAL admin account CANNOT edit a domain account. You can login locally with a domain ADMIN account and then remove it for the domain.

    Hope this helps
