    Hi,

    Today I was attempting to promote a 2003 R2 server to a DC but the error appeared relating to schema issues.

    Now, I only have one other DC (2003 standard) so do I run the adprep.exe (found on the R2 disk) on this server seeing as it has all the FSMO roles? Is it as simple as running the exe from the command line with the following switches - ADPREP /FORESTPREP and ADPREP /DOMAINPREP?

    Cheers,

    Mark

    What is the error message you get when running dcpromo?

    Hi Onoski - I can't remember exactly but it refers to the schema as not being correct (roughly). Like I said the DC is not an R2 server I presumed that running adprep on this machine would 'prepare' the forrest and domain for an R2 DC. My head feels like a fried egg after today - tough day at the office!!

    'The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory'- That's the error that appears after running DCPRMO on the R2 member server.

    I think running this command from the R2 disk on the non R2 server should sort it....

    Drive:\CMPNENTS\R2\ADPREP\adprep.exe /forestprep

    But any further input would be appreciated - Cheers.

    What's the forest functional level of the production dc at the moment also does the active dc show anything in the event viewer at the same time as you run the dc promo on the new dc. Is the new dc a clean install?

    Check to see if the command that you ran worked:

    The correct version of the ADPrep.exe tool for Windows Server 2003 R2 is 5.2.3790.2075.

    You can verify the operating system support level of the schema by looking at the value of the Schema Version registry subkey on a domain controller. You can find this subkey in the following location:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters

    You can also verify the operating system support level of the schema by using the Adsiedit.exe utility or the Ldp.exe utility to view the objectVersion attribute in the properties of the cn=schema,cn=configuration,dc=<domain> partition. The value of the Schema Version registry subkey and the objectVersion attribute are in decimal.

    Schema Version ObjectVersion values and corresponding operating system support level
    •13=Microsoft Windows 2000
    •30=Original release version of Microsoft Windows Server 2003 and Microsoft Windows Server 2003 Service Pack 1 (SP1)
    •31=Microsoft Windows Server 2003 R2

    Alright Dales - the Forrest level is 2000 mixed. So, do I raise the domain functional level then ADprep the Forrest/domain?

    Added to that, it's a clean install of 2003 and then exchange. A re-build after the last DC went tits up.

    Hi Dubfire, thanks for the info but looks like you might have to extend the windows server 2003 schema first. Read through the technet document as it would give you the steps.

    Steps for Extending the Schema

    Let us know how you get on:)

    I ran through the steps and all checked out but when I ran ADprep from the disk it came back with an error relating to it being a valid command but ( I think) because the DC is running a 32 bit copy and the R2 disk is intended for 64 bit OS's. Problem is ive not got a copy of R2 32 bit with me but I do have a self extracting cab file of windows 32 standard. I may go ahead and install that now. Quick one, how do I get the exe cab file onto a bootable disk?

    Cheers once again guys.

    Scrap my last lads. As I didn't have the R2 32 bit disk I ended up installing 2003 standard and went on to complete DCPROMO -

    Cheers lads.
