Network Card Speed and Duplex

P: n/a
Can anybody tell me how to tell what speed and duplex a machine is currently
running at.
It is very easy to find on a switch, however it is incredibly difficult if
not impossible on the PC.

For instance 100Half vs. 100Full vs. 10Half vs. 10Full

I'll take anything utilities, reading material, Log files, Windows API's....

Thanks in Advance

If your NIC comes with a monitoring utility then these will usually tell
you.

Or alternatively, you can force the connection speed/duplex - that way you
know exactly what it's set to.

That's very easy if you see the registry :)
On my machine 0008 - mean one of few NICs ( first ) so :
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4D36E972-E325-11CE-BFC1-08002bE10318}\0008\Ndi\params\SpeedDuplex
show 0
and enum subkey show all options
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4D36E972-E325-11CE-BFC1-08002bE10318}\0008\Ndi\params\SpeedDuplex\enum
