unable to add Windows 2008 R2 domain controller into existing Windows 2003 domain

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?

I believe you are correct in that you need to run the 2008 R2 version of AD prep.  There should be a 32 bit version of it on your 2008 R2 installation disk Adprep32.exe.

The R2 version Schema is different you must run ADPREP from the R2 Media - there is a 32bit version called ADPREP32 - see http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/A_3644-Windows-2008-Server-R2-adprep-adprep32.html

If had run an R2 adprep32.exe from the second installation media it would have done the trick. i think your problem is that you run a non R2 one.Try it again with an R2 one. If you cant find one you can use the trial source disks http://technet.microsoft.com/en-us/evalcenter/dd459137.aspx.
