We have a Windows 2003 server DC1 which is our primary DC holding all FSMO roles. It also is a DNS server for our domain domain.local which is an active directory integrated zone. We also have a Windows 2008 DC name DC2 which is a DNS server with ad integrated zone for domain.local. Both zones are set to "replication: All domain controllers in this domain (for windows 2000 compatibility)"
All servers have the correct DNS entries etc. However in all dns servers dns event log there are event id 4515 indicating there are duplicate zones in separate directory partitions and only one will be used until the other is removed.
And I see these, there is a zone for domain.local under the default naming partition CN=System, CN=MicrosoftDNS, DC=domain.local. As well as the DomainDNSZones partition DC=DomainDNSZones, DC=DOMAIN, DC=local, CN=MicrosoftDNS
It seems that the partition in the Default Naming partition is the one which is being used currently. Which one should be in use? How do I make the EventID 4515's go away? How could this have happened?
