Ping is allowed. All other computers on the network are able to ping out 
to the internet just fine, ,just the one 4.6 box cannot.

The problem described above. It's not getting a connection to the 
network. Oddly, the dhcp server did assign it an address and show the 
box on the dhcp addresses list,  once. For some reason the dhcp list of  
devices it has assigned addresses to drops the two fbsd boxes at random. 
But that's another problem I'm not too concerned with right now. I just 
need to 4.6 box to show a connection to the network. I'll change out the 
nic tomorrow and see if that makes any differance.
