Interesting. I presume my Win32wnet is out of date, since on my system it
produced:

a:\ is removable
c:\ is fixed
d:\ is fixed
h:\ is cdrom
r:\ is remote on
Traceback (most recent call last):
  File "windrives.py", line 19, in ?
    print "on",win32wnet.WNetGetUniversalName(d),
AttributeError: WNetGetUniversalName
