I have a server running win 2000. It is an older server with a Realtek NIC installed. I just connected it from a hub (Half-duplex) to a switch (full-duplex.) How can i find out if my server is actually using Full-duplex now? Is there some sort of command i can run? I checked in the control panel, but nothing relating to my NIC. The new Intel NICs come with a nice utility that will tell you the speed you are running out, if you are running full duplex, and you can even test your connection. Any ideas?
