Well, that's encouraging, in its way :-(. There is no NAT or firewall
involved in my configuration; the client is NT running in a VMWare
window on the server box, connecting through VMWare's pseudo-network
device. (Needless to say, this is preparation for a deployment to
*other* client machines not running inside VMWare processes :-)

I'm eager to learn the result of your experiments.
