Parent and child domain. Parent domain (forest) still in domain functional level 2003. However, child domain i just updated to domain functional level 2008 R2. Now replication is not working. I believe the issue is dns, but i do not know what could be different the names have not changed? This is a two way transitive trust between domains.
Frequent messages from dcdiag dns, are
no DNS RPC connectivity (although i have tried restarting dcom, netbios and frs)
Also in event viewer many 13508 errors
Any help is greatly appreciated thank you.
