  • schema upgrade

    I have three domain controllers running 2003 Enterprise
    DC1 " master" , DC2 " GC" , DC3

    I updated the schema " Windows 2008 R2" on DC1 using adprep32.exe /forestprep and adprep32.exe /domainprep
    when I run schupgr on DC1 give me everything successful upgrade to 47 etc..

    when I run the same command on DC2 or DC3 I get

    SSPI Bind succeeded
    Current Schema Version is 47
    ERROR: Cannot obtain schema version to upgrade to: 1

    everything seems to work okay no replication errors or nothing its just I ran it and I see the error and now its bothering me , read many KB couldn't get into a clear answer especially the winnt32.exe KBS.

    any clues?

    thank you

    The schema only needs to be updated once as there's only one schema partition in each AD forest. You don't need to update the schema on each DC.

      so that error msg doesn't mean anything in my condition
      thank you very much.

        Correct - once the schema is upgraded on the Schema Master FSMO holder, it will replicate to all other DCs on schedule. There is (as you have seen) no need to upgrade on more than one DC
