okay gurus from your experience is this correct?
scenario

4 servers that are DCs and their own primary DNS

example:
DC1/DNS 192.168.1.1 win 2000 PDC emulator
DC2/DNS 192.168.2.1 ""
DC3/DNS 192.168.3.1 ""
DC4/DNS 192.168.4.1 win 2003
All are Active Directory Integrated DNS

Issue:
we use to have all the of the DNS point to self as Primary DNS server
and criss cross the secondary DNS..

First question:
I have heard there is no primary and no secondary in AD integrated!?
true or false explain..


Second Question:
This tech came in and reconfigured all DC/DNS to point to the
PDC emulator 192.168.1.1 to prevent islanding ; he says
so AD can replicate out to each DC cause they cannot find each other
if set the other way. (to point to themselves)

All static IPs on servers and workstations. IPs on servers never change
Local subnets point to the subnet respect DNS/DC for their local DNS resolution.


WTF is he getting at. is he correct? Explain to me I am a dummy then

First point - yes, but with caveats. AD Integrated zones are replicated completely between integrated DNS servers as a 'master' zone. Basically, the AD-Integrated zone mimics a Primary zone and ALL integrated DCs get a copy of it. The only time you should need a Secondary zone with AD Integrated DNS is if you need to resolve a DC in another domain (but we won't go into that here, as it doesn't apply to your situation).

However, there are known issues with AD integrated zones in a non-native W2K3 environment, which leads me on to your second question. Although he probably is just repeating parrot-fashion what he's been told or read elsewhere, there ARE issues with DNS Islanding in W2K.

Its complicated to explain and this article does a much better job of doing it than I ever could!
