Hi Todd,

Hm...I suspect you need to update your version of win32ole.  The
version that comes with 1.8.1 is 0.5.4, but the latest is 0.5.5 (and
will be part of 1.8.2).

Take a look at the attributes available for the
Win32_NetworkAdapterConfiguration class at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/win32_networkadapterconfiguration.asp


If none of those fields fit your needs, you'll have to dig around and
see what you can find.  Off the top of my head I'm not sure.

BTW, I should have a new release of sys-host out this week.

Regards,

Dan
