the current role holder is server 2012 and the server that is being promoted is 2008. I believe the issue may be reside with the SOA record and NS entry in DNS. there are the correct records in the NS. <servername.domain.internal> but also shows <servername.> Also SOA shows <servername.> I have corrected this but when DNS is restarted it reverts back. all the other entries of <servername.> were removed.
the the 2012 server is a cloud server with site to site to the 2008 server. the 2008 server had a replication issue and tomb stoned. roles were successfully transferred, and the 2008 server was demoted and meta data clean up.
here is the error from the dcpromo log:
