DFL doesn't appear to have raised from 2003 to 2012r2


I added a 2012r2 AD/DC to my 2003 domain/forest. I raised the functional level of the forest and the DC's from 2000 to 2003 last night and waited until today to move forward.  I did the migration per instruction in a wonderful online tutorial, step by step with screen shots.

Everything seemed to go OK with replication coming from my secondary DC rather than the one with the FSMO roles.  I did some of the post checks recommended in the article and once again, nothing out of the ordinary however, when i the functional domain level on the old and new controllers, it says it current level is 2003. The 2003 servers say they are operating at the highest possible level.  The 2012r2 server states:

 You cannot raise the domain functional level because this domain contains Active Directory Domain Controllers that are not running the appropriate version of Windows.

The version in the my computer --> properties shows they are running Server 2003 sp2.

Any ideas of what is happening and how to fix it?

Same as the answer I gave to your question on the forest functional level. The 2003 DC means the highest you can go is 2003. That is normal and expected. The highest level any domain can go is the *oldest* DC in the domain, not the newest.

I assumed the op was trying to keep separate the DFL and FFL questions. And while the answer happens to be the same in this instance, I can understand why they were asked separately.
