Hypothetical Question: What if the domain controller crashes?

    We have a domain with only a single domain controller. The system state
    alone is backed up, but nothing else.

    If that domain controller crashes and Windows must be completely installed
    will I be able to restore the domain and its objects if that was the one and
    only domain controller in the domain just by restoring the backed-up system
    state over a clean install of 2000 / 2003 server?

  2. Alan, in this case (full restore) we need restore also c:\ drive fully. So,
    you can ensure that you are going to backup it.

    Hi Alan,

    It is generally recommended that there exist at least two domain controllers
    for any given domain in any production environment. This greatly eases the
    burden when performing an Active Directory disaster recovery. But to answer
    your question, yes, that can be done.
