DCpromo Window Server 2003 R2
Problem:
You are trying up add your new Window Server 2003 R2 to your existing domain as a domain controller. You already ran ADprep.exe /forestprep and ADprep.exe /domainprep without errors. You have waited ample time for the changes to propagate to all servers.
DCpromo fails with this error:
The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command line . . .
“The Version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this coputer.”
Solution:
You used CD1 instead of CD2. You must run the ADprep.exe from CD2. The version on CD1 is for the non-R2 release.
