Question : DNS Issues

We recently migrated our workstations over to a new domain. The domain currently consists of one AD-DC, with a file server and a web server along with 15 workstations. We have a separate location that we would like to add to this new domain (about five workstations and one file server).We have two cisco firewalls between the two locations and NATs set up for all the nodes. Our problem is the second site keeps getting dropped off the domain. I've attached a basic drawing of the network. Question is what do I need to do to get the two locations to talk. I've added a separate dns server (not a DC) at the second location and set up split dns, but still running into problems.

Answer : DNS Issues

We couldn't find a solution to our original problem. But we did do a workaround. We stood up a second dc with dual nics, one NIC has the internal ip of the first network and the second NIC has the internal ip of the second network. It solved the issue of computers dropping off the domain, but brought up the issue of not being able to get to file shares without having dual NICs on all our servers
