    Hello,

    We are planning to raise the functional level from Windows 2003 to Windows Server 2008. Are there
    any known issues with any Microsoft products (SCOM,
    MOM2005, SQL200x or other know issues ?

    Thanks,
    D.

  3. Howdie!
    Not that I am aware of. Functional Level changes change settings and
    behaviors how domain controllers run replication and communication and
    enables features legacy DCs aren't aware of. I wouldn't know of an issue
    that would break SCOM, MOM or SQL in general.

    I'd set that up quickly in a test lab and see how it behaves.

    cheers,

    Florian

  4. None that am aware of but, my biggest concern would be if you had any old
    NT4 trusts, doesn't sound like you have that. I would attempt to build in a
    test lab before you moved forward.

  5. which functional level? Domain or Forest?

    The impact is directly on DCs and possibly on other servers depending on
    what features are introduced by the DCs at a certain level? To give you an
    example... Increasing the FFL to w2k3 (which introduces linked value
    replication - LVR) had an impact on Exchange 2000 deployments (the RUS).
    Why? Because Exchange 2000 did not understand the LVR. It is not the end of
    the world, but it is something to think of as an example. Besides that you
    should ALWAYS test!!!

    FFL W2K8 does not introduce any new features, so no impact there besides the
    fact that DCs with W2K3 and lower OS cannot be present

    DFL W2K8 introduces a number of things, like DFS-R for the SYSVOL, Fine
    Grained Password Policies, new additional encryption mechanism, logon
    information. See:
