Raising windows server 2003 domain functional level and exchange 2

Discussion in 'Active Directory' started by Bill trying to do the right thing!, Nov 26, 2004.

  1. Hi,

    I am planning to raise the windows 2003 domain functional level to 2003
    server(currently 2003 interim). The current IT environment consists of a
    forest with two domains. Each domain has a primary and sec DCs. All DCs are
    2003 servers.
    Also there are two exchange 2000 servers each located in a different domain
    within the forest.

    My Q is, Are/is there any known issue(s) that might impact the exchange 2000
    by raising the domain functional level to 2003 server. Also if for any reason
    the change failed and is unrecoverable (no rollback function in AD) can I
    still restore all DCs AD from backup by choosing the AD restore
    mode............many thanks Bill

    Actually they are "just DCs" -- in Win2000+ DCs are equal.
    (Although one or more of them may hold several special roles.)
    You can also pursue the restore from backup and I don't
    know of any issues -- someone else will likely answer
    here also, but you might consider in the Exchange newsgroups.

    Functional levels really have nothing to so with any machines
    except domain controllers though -- so any interference would
    need to be a bug.

    Forest Function levels -- and Domain modes -- affect only the
    DCs and the capabilities (increasing) of the AD and replication.

    As far as I know there is no known issues with upgrading to Windows 2003
    Server mode in co-existance with Exchange 2000.

    I have do this many times on sites with 1000+ users and have never
    experianced a problen.

    It's obviously a recommended step, as for one you will then be able to start
    creating universal security groups for permissions assignement to PF's.

    The restore mode question is a very good one. My gut feeling is that it is
    not a supported step by Microsoft. Whether it is possible, I have never had
    any reason to try.
