How to determine the Duplex Mode of our PC's

[Mike]

Does anyone know of a command line utility or any other
way to determine the Duplex Mode of our PC's. Our PC's
are configured to Auto Detect these settings but we are
unsure of the mode it detects.

Thank you

Mike

If you are using XP, you can go to the device manager
(right click, then properties on MyComputer, click on
Hardware, then device manager) Select the network
adapter you use, right click then properties again.
Select the advanced tab. You should see 'link speed and
duplex' in the list of configurable options. From there
you can see what your NIC is set for and other available
options. Good luck.
