DCpromo Window Server 2003 R2
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.”
You used CD1 instead of CD2. You must run the ADprep.exe from CD2. The version on CD1 is for the non-R2 release.
