I'd expect it to, but I may be expecting too much from Microsoft. :-)

What names do they have?  The human-readable name that shows up in
"ipconfig" output, or some GUIDful noise such as you saw?

That *does* include the interface list:

and that's the first entry in the list - an interface named only "LAN".

What happens if you type "\Device\Packet_LAN" in the combo box, and try
to start a capture?

At the time you ran "ipconfig", were you dialed in to some site with a
PPP connection?  If not, perhaps the modem didn't show up because it
wasn't currently a network interface (or perhaps WAN interfaces just
don't show up).
