Colin,
The firewall is setup for NAT, I have checked my personal firewall at home
and basically reduced it to nothing. Yet I am still only able to get
authentication on the server (DC), but as soon as I attempt to look further
into the network the connection stalls then eventually disconnects.

I am not sure it is so much an issue with the firewall device, as it may be
a VPN config that I may have missed in AD or something with win2k3sbs.
Thanks for your time and exchange of Ideas. If you think of anything else,
please let me know. If I resolve the issue, I will post for future
refrence.

Sean
