I recently added a new DC to our netowrk everything went
well.
Now i need to know what the promary and secondary DNS
should be on the servers.
currently i have each server pointing to each other for
primary DNS and to themselves for secondary DNS.
each is forwarding to the External DNS server for
internet resolution. Can anyone confirm if this is
correct. or should they point to them selves first then
to the other?
Thanx

Your current setup is OK as long as your not getting errors at startup.

About the only recommendation you'll find at Microsoft is that the first DC
in the Domain is used as the preferred DNS, then any other DC other than
itself as Alternate, this is to correct a DNS island issue. You would
normally only use this setup to reinstall the Active Directory DNS zone.
Pointing to the other first then to itself second will work fine if you only
have two DCs.

thanx for your answer.
now what if i have more AD/DNS servers, then what.
e.g
i have two AD/DNS in domainA.com
then i have three seperate AD/DNS servers in
site1.domainA.com. at a seperate location, both locations
are using different ISP's DNS for internet name
resolution.
