I'm trying to DCPROMO a Windows 2008 R2 server into an existing Windows 2003 AD, When I try to do this I receive an error:
"To install a domain controller into this Active Directory forest, you must first prepare the fores using Adprep /forestprep".
When I do this I receive anithererror stating:
"Adprep cannot run on this platform because it is not an Active Directory Domain Controller". "Run Adprep on a Active Directory Domain Controller".
Can you tell me exactly what I need to do with the proper syntax? Do I in fact use "Adprep / forestprep on my PDC? If so are there any ramifications to my exisitng environment because this is or will be our first 2008 DC?
