Who is Primary in AD Integrated DNS Zones

Question

I have multiple DC/DNS servers in a domain. One previously existed and the other two are newly built. The original will be demoted once the new servers are in place and functioning correctly. When I created the zone on the new DNS servers, I set them up as primary and checked the AD integrated box so now each has a forward lookup zone for the domain and each is AD integrated. Each one shows itself as Primary for the zone. Is this correct or should only one be named the Primary even though the zone is AD integrated? Should I have set the new zones up as secondary pointing to the original?

Thanks

Answer 1

Hi Ken,

Yeah it is correct, I was answering from memory, and which was a little off. The correction is all dns servers will have an individual ns records in the zone, the SOA response will point to the answering dns server.

Answer 2

Hi,

It is correct all the servers will be marked as primary, when the zone is AD integrated . All the servers are listed in the SOA record for the zone.

Answer 3

Thanks Gary,

When I look at the SOA record on each individual DNS server, each one shows only itself as the SOA. For example, DNS_Original will show DNS_original as the only SOA record. When I look at NewDNS_1, it shows only NewDNS_1 as the only SOA record. Same for the second new server. Is this correct or should all 3 each show 3 SOA records?

Answer 4

Thanks, and now for the bonus round...

If I need to create a secondary forward zone in another trusted domain on it's own dns servers, should I enter all three DNS servers we discussed as masters in the secondary zone on the second domain? I'm thinking I should, but would feel better with some confirmation or denial.

Thanks
