Step 6. Master DNS Servers
Here we can enter a list of known DNS servers for the new domain we wish to forward to.
Simply enter the IP address(es) of the other domain to the list. It will validate itself once you add it to the list.
It is important to add all known DNS servers here for redundancy reasons. As I only have the one Domain Controller I only have one address to add.

Step 7. Finished
Step 7 isn’t really a step, however should everything have been successful you should be finished with the final window.
See screen shot below.
Step 9. Consistency
As stated above with the forward lookup zone, if you are looking for complete transparency of both networks, you should repeat steps 1-8 on the example.com network to point to domain.com.
This will result in, not only being able to resolve 10.0.1.0 hosts in the domain.com network (as we have completed above), but also be able to resolve 10.0.3.0 hosts from any example.com host as well.
