Cannot log on to workstation after switching from Domain to Workgr

    We have a network of 30 workstations (mostly XP) and a 2003 server. While
    investigating an outbreak of System Error 4321 (Name "ADOMAIN :0" could not
    be registered) when workstations boot, I switched my workstation from domain
    membership to workgroup membership and re-booted. Now the workstation does
    not recognise my login or Administrator login.

    Can I restore my workstation to domain membership from the 2003 server
    (Active Directory says that it stil is in the domain)? Or get control of its
    login process?
    Excuse my ignorance I am a networking novice who has inherited Administrator

  2. Congrats, you've stumbled upon a very common problem which most
    neophytes learn the hard way. All member servers and workstations
    have a local SAM for authentication on a peer to peer level e.b., no
    domain controller. Once you moved the machine out of the domain
    you cannot use a domain account for local logon. Do you by chance
    know the password for the local "administrator" account. If not you'll
    need to recover it. There are multiple ways. Do a search on the inet
    for "administrator password" and you'll find them.

    Thanks for that.
    I have found a cheap program at which will
    reset the local administrator password - if my predecessor didn't configure
    secure encryption of account names and passwords.
    But first I'll try his car registration code to save the 75euro!

    his house number
    his office number
