I've tried to dcpromo a new Windows 2008 server installation to be a Domain Controller, running in an existing domain. I am informed that, first, I must run adprep/forestprep ("To install a domain controller into this Active Directory forest, you must first perpare the forest using "adprep/forestprep". The Adprep utility is available on the Windows Server 2008 installation media in the Windows\sources\adprep folder".
Trouble is that adprep/forestprep says that:
Adprep cannot run on this platform because it is not an Active Directory Domain Controller.
[Status/Consequence]
Adprep stopped without making any changes.
[User Action]
Run Adprep on a Active Directory Domain Controller.
So, which needs to be installed first (they cannot really be dependent upon each other), and how do I go about completing this?!
Thanks
