DHCP standards say that a machine that reconnects requests that it be reassigned the IP it had prior to disconnecting. If the IP is still available, the server should reassign the same IP. Thus, if you're only disconnected for a few minutes, the chances are very good that you'll get the same IP and the transmission will complete. I will give MS credit here. Their systems seem to request and reuse the same IP as per specs when using DHCP. -Bill -- If a bird in the hand is worth two in the bush, then what can I get for two hands in the bush?
