A Windows 2000 domain controller also provides DHCP services to the Windows 2000 Pro clients. All servers are static. > 3] Are you using a Wins Server for your domain? The domain controller currently provides WINS and DNS services. > 4] For how long does the connection stay off-line before coming back? This period seems to be indefinite based on unquantified observations. I have not timed this period. A few times it seemed never to come back up. I even tried ifconfig nge0 down && ifconfig nge0 up to re-initialize the interface. This didn't help. Rebooting the server fixed the interface in these instances. > The reasoning behind the above is the fact that this might an issue of > how (if this is so) MS Windows clients on dhcp maintain respective > connections over the network during data transfer - You may well be > seeing cases of timeouts on the client end here.
