    We are running Windows 2003 domain on 32-bit system. I am trying to
    promote my first Windows 2008R2 to Windows 2003 domain but I keep
    getting the message saying that I need to adprep, which I already ran
    "adprep /forestprep and adprep /domainprep" on the primary domain
    controller which holds FMSO and also global catalog.

    I wonder if the problem is between 32 bit and 64 bit. Can someone advise
    on this?

    Thank you very much!!!

    32-bit vs 64-bit should not be a problem.

    Make sure to insert the Windows 2008 R2 DVD in the Schem
    master and run "adprep /forestprep". Insert the Windows 200
    R2 DVD in the Infrastructure master and run "adpre
    /domainprep" on the Infrastructure master.

    Make note of any errors or messages you get when you ru

    After doing so, you must wait for replication to occur
    Depending on your infrastructure and replication schedule
    this make take some time. Once it is done you should be abl
    to promote a 2008 DC.

    If you're still having problems then run the typica
    diagnostics like dcdiag, replmon, etc. to spot troubl

    Run on a 32bit machine, use adprep32.exe (from the R2 DVD)

  4. Hello april,

    As already said from the others, make sure to use the adprep32.exe from the
    Windows server 2008 R2 disk on the schema master.

    Best regards
