Indentify primary DNS server in AD

Folks

Probably a fairly trivial question but for the life of me I can't seem to find an easy answer.

I have just "inherited" the management of a fairly complex - and undocumented - AD infrastructure.

Is there any easy way to locate where is the "master" DNS server in the infrastructure (I sure hope there only one :) ?

Any suggestion most welcome

Regards

If it is active directory intergrated, you don't really have a master DNS.

Hi,

If your domain infrastructure is 2k, 2003 or 2008, if it is AD integrated. Then there wont be any master DNS in that...!

All can be a master..!

If it is not AD integrated and using a stand alone then you will have Primary DNS and secondary DNS...!

Hope this helps your question...!

Regards,
Prem

You need to understand that with AD theres not always a "master" DNS server.
If the zone are AD integrated, then it depends of the scope of replication for the zone.
It can be :
- every DNS server in the forest (every DNS server in the forest will have a read/write copy of the zone)
- every DNS server in the domain (every DNS server in the domain will have a read/write copy of the zone)
- every DC in the domain (the DNS zone will be stored on every DCs) but only DNS server can update the information.

Replication occurs through AD, theres no master.
It exists a SOA for the zone, and NS associated, but all of them can update the records in the zone.

If the zone is not AD integrated, then you can review the SOA:
nslookup -type SOA zone.com
