I posed a question a couple of weeks ago and had no response so I'm hoping I just worded it badly. I'm desperate to sort this out so I'm having another try.
The first error I got in my DNS log was Event ID 4515 "The zone contoso.com was previously loaded from the directory partition ForestDNSZones.contoso.com but another copy of the zone has been found in directory partition DomainDnsZones.contoso.com. The DNS server will ignore this new copy of the zone. Please resolve this conflict ASAP". I now get it the other way around too with Forest & DomainDNS zones reversed.
Apparently the way to correct this is to use adsiedit.msc to delete one of the zones but it says to confirm that a duplicate zone exists before doing this. So I went in and had a look using adsiedit.msc and sure enough there are records in both forest and domain DNS zones. But they don't look the same.
The Forest zone within DC=_msdcs.techset.local contains the following:-
DC=@ DC=_kerberos._tcp.dc DC=_kerberos._tcp.Default-First-Site-Name._sites.dc DC=_ldap._tcp.48b60e56-...etc. DC=_ldap._tcp.dc DC=_ldap._tcp.Default-First-Site-Name._sites.dc DC=_ldap._tcp.Default-First-Site-Name._sites.gc DC=_ldap._tcp.gc DC=_ldap._tcp.pdc DC=10d556611-...etc. DC=677cc99c-...etc. DC=arwen (this is a new DC which has the same name as my old PDC) DC=c8721c1-... DC=gc DC=legolas (this is my PDC)
There is no mention of the other DC on the network.
Also within the Forest Zone in DC=254.168.192.in-addr.arpa are all the pointer records for the whole network.
In the Domain Zone under DC=techset.local there are:-
DC=A DC=_gc._tcp DC=_gc._tcp.Default-First-Site-Name._sites DC=_kerberos._tcp DC=_kerberos._tcp.Default-First-Site-Name DC=_kerberos._udp DC=_dpasswd._tcp DC=_kpasswd._udp DC=_ldap._tcp DC=_ldap._tcp.Default-First-Site-Name._sites DC=_ldap._tcp.Default-First-Site-Name._sites.DomainDNSZones DC=_ldap._tcp.Default-First-Site-Name._sites.ForestDNSZones DC=_ldap._tcp.DomainDnsZones DC=_ldap._tcp.ForestDnsZones DC=_msdcs DC=DomainDnsZones DC=ForestDnsZones DC=Aragorn DC=arwen DC=Ben DC=Bilbo etc. (all records for all computers on network)
Sorry for so much typing but my question is this. Is it normal for the Forest zone to have so few records in it? I'm really asking which one I should get rid of. The forest zone is missing records for 1 of my DC's and doesn't have any DNS records apart from pointer records for the network. Is that normal? And the Domain Zone doesn't have any pointer records at all. Which one should I delete?
I'd really appreciate an answer if anyone knows!
