Check Duplex on NIC

[MasterofNone]

If I remember right, when we ran NT on all our client machines, I could visit a desktop and check it was picking up 100mb full (had problems in the early days of going multicast). If it hadn't I would force the NIC to 100full and if connection dropped get the port reconfigured (after patching to a working port).

Now my question is this. Whilst checking 10 or 100mb is simple in XP, haven't yet found a way to make sure it has autonegotiated to full duplex. Anybody have any answers (not something I want to keep bothering our Cisco engineers with. i.e. making them check the port).

There is no native utility or WMI monitor to tell you the duplex setting resulting from autonegotiation.

XP's specifications for a WHQL driver for lan adapters does not require this information be returned by the driver, and I am not sure why. As a guess, it is kind of a pain to implement.

Typical MS attitude. Thanks anyway

You should be able to query the Cisco switches and get a return on their status.
