WMI - Network Card settings

I'm trying to query network cards for a certain setting.  I've tried to find the setting in WMI or any other way I can script out a solution.  I need to be able to tell if the check box is checked or unchecked.    To get to that screen go to your network connection, properties, authentication tab, then settings.

I would like something I can do in powershell preferably

I tried following your steps to get to this screen but am unable to reproduce. I am using an XP machine.

Do you have an authentication tab at the top?

I didnt at first. I had to start the wired autoconnect services in services.msc. I am looking at this now. Hopefully post back with some good news.

So I just looked through the WMI and it doesnt look like this setting is configured in there. Doing some more digging it looks like this setting is configured in the registry.

Take a look at the EE question below for the path of the reg key.
