Unable to promote 2012 server to DC

Hi,
I have a 2003/ 2008 domain with the intention of adding a 2012 r2 server.
I have completed all requisites to include adprep /forestprep, adprep /domainprep, and adprep /domainprep /gpprep.
also im sure before i started i confirmed that the FFL was 2003.
Unfortunately while trying to promote the 2012 server i get:
" verification of replica failed. the ffl is windows 2000..."
i went back to check the FFL, but now it only shows DFL 2003.
the next problem i see  after running schupgr.exe
SSPI Bind succeeded
Current Schema Version is 69
Upgrading schema to version 47

also i have confirmed replication is working, time is right, and 2012 is up to date.

1. RECONFIRM the Forest Functional Level
2. Run DCDIAG /C /E /V on your existing DCs and make sure they both see things as normal and functional - this should be the first step whenever promoting a machine to be a DC.  And of course, correct any unexplained errors.
3. Ideally, after you have done 1 and 2, to ensure we have exact information, please post screen shots of the error(s) you may have.  (If you want to post the DCDIAG results, go ahead, but PLEASE attach them as a text file!)
