  • Domain is 2000 Native can I raise it 1 level to 2003 or even 2008?

    MY domain is Windows 2000 Native... All the DCs have been Windows 2003 for a long time.

    Can I raise the functional level one evening to Windows 2003 Native or mayeb even WIndows 2008?

    I am usually very careful and we have a medium/large environment with 30 Citrix servers/SQL/Exchange/etc..

    Anything I have to do or be aware of before raising the functional level?

    What are the exact steps for upgrade (just right click - upgrade)?
    I do plan to take offline 2 of three DCs in case of recovery and the DC that will get the upgrade will be offline (ethernet off) during the upgrade.

    Any help greatly appreciated.

    I don't recommend making changes to the schema while domain controllers are offline.

    Also, I would have thought you would need Server 2008 DCs to raise the functional level to Windows 2008.

      Correction - to raise it to Windows Server 2008 you absolutely must have ALL your DCs at Windows Server 2008. I don't know what the new "Intermediate" Functional Levels are with the new OS, but for them you need to have at least one WS2k8 DC.

      With all your DCs at Windows Server 2003, you are not getting anything like the best features of a W2k3 domain until you have your Domain and Forest at Windows Server 2003 functional level. You should raise the level as soon as you can... it is non-destructive and requires only a few clicks; look at the Microsoft Article here for a thorough set of instructions and pre-action checks.

          Re: Domain Functional Levels

          Then the proper way is to leave all 3 DCs online and raise the functional level on one of them and let it replicate to others?
          Any gotchas for the rest of the servers/environment/citrix/Vmware?
          maybe introduce win2008 DC in win2000 native mode like all other DCs, then raise the functional level on that win2008 DC to win2003?

          Thanks
