We have a couple of different scenarios.
The first: DNS is on a Windows Server 2012 R2 DC. Let's pretend this server IP address is 192.168.42.31.
The second: DNS is on a Windows Server 2012 R2 Member Server.Let's pretend this server IP address is 192.168.42.51.
My question: How should the IPV4 Properties be set for the Preferred DNS Server and Alternate DNS Server in each scenario? I've read/heard different things--and had some weird results when I've implemented some suggestions--and I want a definitive "This is what you should do and why." type of answer.
I grabbed the picture below from the net just in case it will help explain what I'm looking for.
Not that it signifies, but we do allow DHCP to update DNS.
In that case, DNS should be integrated into AD so that changes replicate easily and quickly to ALL DNS servers.
You NEVER, EVER, put a NON-AD aware DNS server into your servers or clients network properties. I don't know if you've enabled zone transfers or if a member server's DNS can be stored in AD (in part because I wouldn't and I don't know anyone who would set it up that way). If not you have problems.
