    I have a shop with about 22 2000 servers all are standard
    edition. I want to gradually upgrade to 2003. I would like
    to start with the domain controllers. Will there be a
    problem if not all domain controllers are upgraded. Once I
    get a DC's converted I want to upgrade my Exchange server
    to 2003. What benifits will I get if it is enterprise

    The Exchange stuff I can't answer (and also we're in a migration NG, so you
    may want to go to the Exchange NG for those answers), but as far as your
    questions dealing w/ W2K3...

    Windows 2003 will run in Mixed Mode for your domain and forest, which allows
    for backward compatibility with 2K DCs. No issues here. Keep in mind that
    DC's and member servers are two different animals. In other words, you can
    go to W2K3 native mode once all your 2K ***DC's*** are 2k3. Your member
    servers can remain on 2K forever and it won't effect anything.

  3. Hi Ben,

    Thanks for your posting here.

    You do not need to upgrade all the DC to Windows 2003. Windows 2000 mixed
    (Default) and Windows 2000 native mode both support Windows 2000 Domain

    For more information about Windows 2003 domain and forest function levels,
    please refer to the following documents.

    Please note that you first need to run adprep to extend AD schema in the
    Windows 2000 domain. Please refer to the following articles for the
    detailed information.

    Have a nice day!
