This is not an NT domain based environment - just your regular workgroup networking technonolgy. I have played with udp 137 and 138 but cannot get an inside Windows PC to see the outside machines in the network neighborhood part of windows explorer. And obviously, at the moment - the inside PC cannot access any drive shares on the outside. Configuration guidance would be very very appreciated.
