Is there a scriptable method for testing duplex settings on network interfaces?

Question

I'm looking to test, on a large number of servers, whether or not the duplex settings on the network interfaces have been set up properly.

Is there a tool, or set of scripts, which I can run against the servers, to test their settings?

The servers in question are Windows 2003 and windows 2008 machines.

Duplex setting is very eratic with regards to scripting support. Some vendors (such as Intel) give a WMI provider that gives it, others write to the registry and text files blah blah blah. You can get link speed pretty reliably, but duplex settings can be problematic.

I wonder if this might be more reliable through SNMP. – John Gardeniers Jan 05 '10 at 22:48
I'm looking for any automated test, really, which can reliably tell me whether the connection is set to full-duplex. – blueberryfields Jan 05 '10 at 22:52

You're going to have a lot better luck getting that from the switch than from Windows thanks to, as squillman says, NIC driver inconsistency. – Evan Anderson Jan 06 '10 at 00:53
