Hello Everyone,
I am trying to determine what the best practice approach is for our 3 domain controllers in our Active Directory domain. Specifically, I am trying to determine what the Preferred and Alternative DNS entries should be for each of our 3 domain controllers.
Our environment is a bit unusual since we have Infoblox as our DNS\DHCP server and AD as DNS only. I included a diagram (see attached) to help illustrate this. Do the domain controllers need to explicitly reference each other as preferred DNS servers? MY guess is that the preferred DNS server for DC1, DC2 and DC3 should all be the infoblox name server at 10.10.10.10. but then what should the alternative DNS servers be? TIA
