The only exception observed was at line 300 of SmbSession jcifs-1.1.9 wchi was
caused by the XP having apparently logged me in as 'guest' (according to the
boolean on response) and my name not being guest.

The presented credentials were a valid username, and password for the XP
machine, since it was  a workstation I tried using it's workstation name, then
it's workgroup name for the 'dom' with the same results.

On the 2000 box the 'dom' field appeared to be ignored. But authenticated or
didn't based on valid user/password combinations.
