The tool to use, in order to get the names of interfaces on your
machine, is called "tethereal". :-)
Run Tethereal with the "-D" flag; it will print the names of the
interfaces it knows about. Given that you're running Windows NT 5.x
(Microsoft insists on calling the desktop version of NT 5.1 "Windows
XP", for some reason) rather than 4.x, the name will probably be
something hideous such as
\Device\Packet_{BE4BA606-1F72-48CA-87CF-4F1693D8F544}
However, if you start Ethereal 0.9.1, select "Preferences" from the
"Edit" menu, select "Capture" from the pane on the left, select the
token ring interface in the "Interface:" box, click "Save", and click
"OK", then both Ethereal *and* Tethereal will default to using that
interface. ("-i" can still be used to override that default, and you
can still set the interface in the "Capture Options" box popped up when
you select "Start" from the "Capture" menu in Ethereal.)
