i have two locations in my company let us say X and Y. both locations we have one Ad integrated dns and one legacy dns(stand alone dns for internal name resoultion) both locations are connected using mpls .we need to have ad +dns redundany in both placess
if failover happenns
our clients in both location preffedrd dns is ADdns and alternate Dns is legacy dns .if our ADdns fail we need to work client by authenricating ADdns in remote location .for this we have made a forwarder in legacy dns to other location ADadns .both Ad are
replica servers
but when assume X location ADdns fails name resoultion not happening . i mean when we ping domian name it is trying to reach x locations ADserver (failed one) .it is not forwarding traffic through legacy dns to reach other locaton DC

I think that your reasoning is not correct. In internal environment use always DNS that contain standard and resource record. If you have DNS that does not contain RR, then in the case of failing "true" DNS, then you are lost.

Hi,


This type issue should be more related to Server site. You may get the more solid suggestion on Server Forum.
