Please suggest how and where to add this IP subnet in the windows AD so that branch office different IP subnet gets resolved with main office Windows AD, please help with steps on “HOW TO”

Nothing to do but make sure clients use your domain controllers for DNS.

If you have DCs in more than 1 physical location, then you should have AD Sites and Services configured.


Thanks for the reply, My AD network is 109.0/24 and branch office connected over MPLS are of 114.0/24 hence should I have to add/include 114.0/24 in windows AD DNS config please suggest where and how to add.

You don't have to do anything.

Will you have DCs at the new site? Do you have DCs st any site other than the main one?

The one thing you may want to do is configure a reverse DNS zone, if your existing reverse DNS zone doesn't already encompass the new IP addresses.

If your reverse DNS is 168.192.in-addr.arpa you are set. Otherwise you can add 114.168.192.in-addr.arpa as a new reverse zone, and then your reverse DNS will be set.
