Join a member server to domain which is on a different IP range


Ive got a W2k12 member server based in one office and the ip range is 192.168.27.x. I want the server to join the domain which sites on a different ip range 192.168.170.x. I can ping the main DC which sites on from the server 192.168.27.x. Im trying to join the server at 27.x to the domain in the 170.x its never finding it.

The two networks are connected via a permanent VPN connection.

How can I achieve this?

As long as the member server can ping the DC you are good to go, it's not necessary for them to be on the same subnet to join the domain.

From your member server, configure the DNS to point to the DC (assuming that's where DNS is installed) be sure to make sure "Register this connection's addresses in DNS" is checked.  After that from the member server run the following command:

IPCONFIG /registerdns

Be sure the client accounts were added to the DNS forward zone on the domain controller, once done, you should be able to join the domain.
