I am having some replication problem between mt DNS servers, so I want to know for each DNS server which one should be listed as primary?
Example:
I have DNS1 now I want to add DNS2. In DNS2's network properties under DNS which DNS should be listed first on DNS2 should the first DNS server be it's own IP or the IP of DNS1

The first DNS on the Network Would be the Primary DNS on all the Network Server.
Unless you have a closer server (physicaly) to be your Primary DNS.
So That, in your Case I would Say to Make DNS2 a secondary zone of the DNS1 and use DNS1 on this Server as a Primary.

MS recommends if they are AD-integrated DNS servers that each server should always have itself, and only itself, listed as both primary and secondary. Even if they are not AD-integrated, I would recommend the same, because if the primary server is down, and the secondary server is looking for the primary server for DNS resolution, it will be a lot slower than if you have it set to itself for primary DNS. Perhaps if you could describe exactly what replication problems you're having - I'm not sure which DNS server is listed as primary has anything to do with replication. Hope this helps!

Ahh the DNS days,

I belive the old ways are the best ways.

DNS1 Primary
DNS2 Cache

If you have more the two it would be as follows

DNS1 Primary
DNS2 Cache
DNS3 Secondary
DNS4 Cache

This will provide you with reliability and speed in the dns relm.

Hope this helped
