I have a single AD Controller in a simple domain.  It's running schema version 44.  Win Server 2008 Ent 32 BIT SP2 installed.

How can I take that up to schema 47 so I can add another DC running 2008 R2??

I have to run adprep, but from which disk?

Thanks!

Here is what the versions will mean:

47 = Windows Server 2008 R2
44 = Windows Server 2008
31 = Windows Server 2003 R2
30 = Windows Server 2003
13 = Windows 2000

You need to use adprep32 from Windows Server 2008 R2 DVD set. Run it on your W2K8 SP2 server

adprep32 /forestprep
adprep32 /domainprep

That's enough for now. After installing R2 as DC you can tranfer FSMO roles if you want to. But if not, leave them.

Is there a 32BIT version of 2008 R2?  I've created a server running 2008R2 64 bit and it's currently not a DC.  But, when I try to run adprep from the 2008R2 64 bit disk on my 2008 SP2 32 bit DC, it won't let me.

That's right. Dariusg is right. R2 is only 64 bit and you need to use 32bit adprep on your W2K8 SP2
