Hi James,

Can you please get two captures:

 1) Windows client (e.g. XP) successfully listing the target read-only share
 2) JCIFS failing to list the same target share.

JCIFS and Windows should be identical so apparently that is not the
case (or Windows trying and failing as well and falling back to trying
something else).

I'll compare the two captures side-by-side and see if I can figure out
what the problem is.
