I completed an in place upgrade of a 2003 Domain Controller (x32) to a Server 2008SP2 Domain Controller (x32).
From the 2008 (x32) media I ran adprep /forestprep and adprep /domain prep /gp without errors.
I am now trying to dcpromo a 2008R2 (x64) Member Server to the same domain previously prepped for 2008SP2 (x32) successfully.
I receive the message:
---------------------------
Active Directory Domain Services Installation Wizard
---------------------------
To install a domain controller into this Active Directory forest, you must
first prepare the forest using "adprep /forestprep". The Adprep utility is
available on the Windows Server 2008 installation media in the
\sources\adprep folder.
Am I correct in assuming the reason I have to run adprep /forestprep and adprep /domain prep /gp again is because we're adding a 2008R2 Domain Controller (x64) to the domain for the first time? Is that correct?
