Just installed AD again and have come up with a few interesting problems. The main on is...

Source: IPNATHLP
ID: 31003
The DNS proxy agent encountered a network error while attempting to receive messages on the interface with IP address 2.0.1.0. The data is the error code.

The thing is there is no real official NAT hardware installed just a couple of NIC's but then when using Routing I would prefer to try and use the NAT for firewalling instead of just the basic firewall.

Any suggestions?
