I am attempting to add my first Windows 2008 R2 server into my domain as a new domain controller. I have a Windows Server 2003 SP2 32bit domain controller currently. I ran the adprep /forestprep command using a Windows Server 2008 32 bit media kit (non R2) on the existing 2003 machine.
Running the dcpromo on the 2008 R2 machine fails. It gives an error that the adprep /forestprep command still needs to be ran on the existing 2003 machine. I'm assuming a 2008 R2 version of the adprep needs to be ran to upgrade the network and not a standard 2008 version? This can't be accomplished as the 2003 machine is 32 bit and the 2008 R2 is 64 bit only.
Any way around this?
