DNS on secondary setup wrong

Posted on 2008-06-17
Last Modified: 2011-10-19
I am deploying a new server and it is going to be a secondary DNS server.  It has already been configured as a primary dns server.  When I attempt to delete the zone, it gives the warning that it is an AD integrated zone.  Server 18 is to be the primary DNS and Davis-RKP is to be the secondary.  If I delete the zones under the Davis-RKP server will it affect the zones under the Server18 server? (see attached pic)  Or can I just change the Zone Type under Davis-RKP from Integraded to Secondary.  

Thank you very much.

Is there any reason that you are not using AD Integrated DNS?
This is much more efficient and allows you to have multiple primary DNS servers and i is a lot less hassle.

Are both of these servers domain controllers?  If so, why not leave them as AD Integrated.  The pros of AD Integrated certainly out weigh the cons.  There is no advantage to a secondary zone over and AD Integrated Primary.

The book that I was reading made it sound like it can be bad to have multiple Primary DNS servers.  You should have one Primary and the rest should be secondary.  I plan on leaving server18 (what is our primary dns server) AD integrated.  I just wanted the Davis-RKP to be a secondary.  If I leave it as a primary, and I need to make a change to anything do I have to do it to all of the servers or can I just increment the serial number and it will replicate to the other DNS server?

Thanks for the amazingly fast reply.

Not at all. AD Integrated DNS is more secure, integrates fully with Active Directory, if more efficient as it uses AD replication rather than relying on zone transfers and as it uses the multi-master model there is less latency as all servers can update each other. AD Integrated DNS should really be used as the default and you have to have a good reason not to use it, rather than justify its use.

Thank you.  I will leave it as AD integrated then.  Let me make sure I understand updating it then.  If I update any of the DNS servers, it will replicate to any other AD integrated DNS server?  Do I need to increment the serial on the SOA on the server I am updating or will it do that automatically when I make a change?

Make the change on any server and when replication occurs the other servers will be updated automatically - no need to do anything

Wow. Thank you for your fast responses.  I've been toying with joining EE for a long time and this one had me stumped so I tried a trial.  I will be joining permanently now.  Thanks and expect a LOT of questions in the future.
