Windows (explorer, etc.) will use the cached credentials of the currently
logged in user (when accessing either remote or local shares).  Effectively,
when you log in Windows remembers the username and password entered and uses
that for subsequent authentications.  This is why you don't get prompted
to enter a password later.  jCIFS can't use the cached credentials, which
is why you need to enter a username/password.  If you don't, jCIFS will use
the GUEST account (as Mike noted), which would typically have significantly
restricted access (if it is even enabled).
