I am trying to deploy a Windows 2003 Standard R2 x64 server into a domain with existing Windows 2003 32-bit domain controllers. I followed the directions found here: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Q_22993975.html
but was told by adprep /forestprep that it could only be run on a Domain Controller.
From what I've read, this is not the case, I should be able to run it from the new server as long as it is joined to the domain.
Am I doing something wrong?
