Hello

I have a windows 2008 R2 64BIT server in a 2003 domain. Functional level 2003
Prior to the the 2008 R2, I had the 2008 Standard which I had DCPROMO to my first 2008 DC. I then realized we installed the wrong edition of 2008. It should have been 2008 R2 so I demoted the 2008 STD server and rebuild the server with 2008 STD R2, I add it to the domain and tried to DCPROMO but this time its telling me I have to run the adprep /forestprep etc. I ran these all before and was able to successfull DCPROMO the original server with no problems. Why am I now getting this message and the dcpromo fails

I am now removing the server out of the domain back to a workgroup and starting again
Any ideas

Windows Server 2008 R2 includes new Active Directory schema so the forest and domain must be prep'd using the Server 2008 R2 installation disk before a 2008 R2 server can be promoted to a DC on the domain.

Server 2008 R2 is not the same as Server 2008.  (It's like Vista = 2008, Win7 = 2008 R2 - they are not the same), so a different AD PREP is required.

Just only to add. If your 2003 DC is 32bit you have to use

Adprep32 to prepare your forest/domain for new 2008 R2 DC

Yes, you have to run the ADPREP off the R2 media.
