What is the current duplex state on a PC network interface?

Hi all,

Is there a tool out there that you can run on a server or any windows
platform for that matter, which will tell what is the current duplex state on
a NIC? I know that there is an NDIS OID for this:
OID_GEN_MEDIA_DUPLEX_STATE. Do you know of a tool that uses it? I used to
be able to do this back in my network engineering days by looking at the
switch but I can't do that now.

Thanks!

I answered my own question.

The only thing I have found so far is that the duplex state shows up in the
system log in the information entry for the network driver (The System log
source field would have the network driver name.).
