Ugh, top-posting...  Reformatted.

Umm, you *did* read my *whole* reply above, right?  And you did follow the
link I provided, right?  I said that rsh does lose the permission
("doesn't have the same privilege", rather).

In short (to reiterate the content of the link), you cannot access network
shares that require password authentication when logging in without a
password.  This is a Windows limitation, and Cygwin can do nothing about
it.  Either use a password to rsh, or change the share permissions to not
require a password.
