    Is it possible to be able to have active directory
    running on both a 2000 server and 2003 servers
    simultaneously or does this just cause problems on the
    network with the differences between the 2 different
    controllers? Is it best to just upgrade all domain
    controllers to 2003 in one big sweep? Thanks for any and
    all replies.

  3. Hi Steve,

    Thanks for your posting here.

    Windows 2000 DC can coexist with Windows 2003 DC in a same domain when the
    domain is in the Windows 2000 mixed (Default) and Windows 2000 native mode.
    Before you upgrade Windows 2000 DC to Windows 2003 or add a new Windows
    2003 DC, you need to run ADprep tool to extend the AD schema first.

    Please refer to the following article for the detailed information:

    In addition, you can also refer to the following article for the Domain
    Functional Level in Windows 2003.
