    I bought a new Dell server with Windows 2003 R2 on it. I have a Windows 2003
    Domain with SP1 in Windows 2003 Domain Mode (highest). All my DC's run
    Windows 2003 SP1 (not R2 though).

    When I run DCPromo on my new server it says that the Schema isn't compatable
    and I have to run Adprep /forestprep and Adprep /Domainprep. I had done that
    already when I upgraded from Windows 2000 Server. I even tried to run it
    again on my DC's and it says that it has already been run.

    I am baffled? Any ideas?

    Hope that all is well down in San Diego (if I have that wrong, please excuse

    Windows Server 2003-R2 is version 31 whereas Windows Server 2003 is version
    30. So, you would need to take CD2 from the R2 set and run the usual
    suspects. Have you done this? The key is that you have to use the 2nd CD
    (CD2) from R2.....

    Thanks. I live in Victoria, BC Canada but all is well up here too. You would
    have thought that when Releasing R2 they would have put the correct copy of
    ADPrep in Disk 1 as well as Disk 2. I never would have figured to try finding
    it on Disk 2 because there was no i386 and it was not obvious. I searched for
    ADPrep on MS website and did not get any article or KB on the subject.

    Luckily this did the trick. Thanks

  5. Even if you have run ADPREP when upgrading from Windows 2000 Server to
    Windows Server 2003, there are still some more schema additions to Windows
    Server 2003 R2 that need to be setup. Use ADPREP on the R2 disc, and it
    will prepare your domain for R2.

    Sorry. Not sure why I thought that you are in San Diego!?!? Anyway, glad
    to hear that things are going so well.

    You are not the first - and will not be the last - to have a hard time
    figuring out where ADPREP is for R2. I know that there are a ton of
    articles out there for it...I will find some for you.

    I know that Paul Williams has this on his web site
