I have a single server 2003 domain controller and I am trying to promote a server with server 2008 R2 (64 bits) as a domain controller.
When I run the dcpromo on the 2008 R2 server, I get an error message that I need to prepare the forest.
When I run adprep.exe from the server 2008 R2 disc on the current 2003 server I got that error message that say the the adprep is valid but for a machine type other than the currnt machine.
The 03 server is running server 2003 Standard edition and the server 2008 server is running server 2008 R2 64 bit.
Any thoughts on how to fix this issue?
