I replace my old Domain Control windows 2003 server to new in 2008 R2. My current functional level is 2003. I am preparing my forest and my domain with adprep. I gild and already the operation using a CD 2008 and everything seems ok. Do I perform the same operation with the adprep sources of my 2008 R2? Is there a difference in the pattern between the 2008 release 1 and release 2? The reason I ask is because I tried to do it using my cd adprep32 R2 gold I returned the following error: "Program too big to fit in memory". Please help.
