    I have a domain that has to domain controllers. It was originally a 2000
    domain, but later i upgraded (both domain controllers) to 2003. Now I am
    trying to add a brand new 2003 server as an additional domain controller.
    However I keep getting an error that says the schema don't match? I checked
    and the controllers are both running in native mode. Any help would be

  2. I'm betting that the one you're trying to add is a Server 2k3 R2 version. I
    don't remember there being a schema change with SP1 (which is the minimum
    level that Server 2k3 x64 Edition would be). If so, there's a schema update
    as part of the R2 package.

    It's easy enough to fix - use adprep to update the schema and then try
    again. See for the updated adprep.
