maplelf.com as forest level domain and mlflexserv.com as second domain
ad5 is the primary dns server in maplelf domain and is a 2003 server. I just added a new doiman controller in the mlflexserv domain to replace the one we had. AD promotion went ok and active directory is replicating fine. I can't get the new dc to get a zone transfer from ad5. I reduced the ttl on both servers to aid in troubleshooting but it's been many hours and nothing has shown up on the new domain controller which is 2008 r2 btw.
I have made sure each servers has the others info configured in the name servers tab and have allowed zone transfers. Am I missing anything?
