Adding domain controller to existing domain

I have a Windows 2003 domain controller and am adding a new Windows 2008 R2 64-bit domain controller to the environment. I used the Windows 2008 R2 CD and ran adprep /forestprep, adprep /domainprep, adprep /gpprep, etc. and all was fine. When I try to add the 2008 server to the domain using dcpromo it says that the forest must be prepared by running adprep /forestprep. If I re-run adprep /forestprep on the 2003 domain controller it says that it has already been run and the forest has been prepared.

You need to run ADPREP on the FSMO master DC (well, there are certain roles that are specific, but in your case, I suspect you only have one DC with FSMO roles).  Further, make sure you use the correct DVD.  2008 and 2008 R2 are different versions and if you run ADPREP using 2008, you're not preparing for 2008 R2.

Also, if the 2003 server is 32 bit, then you need to be running ADPREP32 instead.

ADPREP32 is not on the 2008 R2 CD, only ADPREP. A search on the CD only returns ADPREP.

Where did you get the DVDs from (2008 R2 is WAY too big to fit on a CD)?

I would say review this:

And look CAREFULLY at the media you are trying to use.

What is the current functional domain/forget level? Win2003 or lower?

From where?  You're best friend Bob?  Downloaded ISOs?  A torrent site?  WHERE?  If it's legit media then you have a folder DESCRIBED in the link I provided with ADPREP32.  Again, you only need that if you are running the 32 bit version of Server 2003.

If your DVDs don't have the ADPREP32 file, then you have the wrong DVDs you're trying to use.

Here is a screenshot of my 2008R2 DVD:
