The DNS Server entry on exodus is configured wrong.
I am assuming that a valid DNS server is running on Exodus along with AD seems how
it is a DC. This is why genesis2 is pointing to exodus (192.168.2.10) for DNS.
Therefore, the primary DNS server entry for exodus should be 127.0.0.1, which tells
it to look at itself for DNS services. The DNS server on exodus must then have a
forwarder configured that points to 192.168.2.1 which is your gateway.
The settings on genesis2 are correct.
The domain you should be trying to join is server607.com.
