I have found plenty of articles that address Server 2012 R2 on a functional level 2003 domain. What I haven't been able to find is anyone addressing weather or not a 2003 server would be fully operational in a 2012 functional level domain. Can anyone confirm that it would work?


A simple 2003 member server will have no problems working in a 2012 (or 2012 R2 for that matter) functional level domain. But you won't be able to have a 2003 server running as a DC.

  • Yep, it'll run just fine as a server, but it cannot be a domain controller(or probably much else). Oct 10 '14 at 16:55
