We just purchased a new server that I would like to make a secondary domain controller in our domain. The original DC is running SBS 2003 SP2 (not R2). When I try to DCPROMO the new server I get the following message during the AD install:
"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer."
I understand that I am supposed to run the "adprep" tool from Disc 2 of the Windows Server Std 2003 R2 installation set. Am I supposed to run this on the new server or on the original domain controller?
If I am supposed to run it on the SBS machine, what are the implications of doing so? Are there any serious problems that I might expect to run into when running this on an SBS box?
