I believe this is usually possible. It may be necessary to use the laddr property.
Beware however that some machines/OSs like Windows 2000 on a laptop may shutdown
the ethernet controller to conserve power which may also effect localhost
communication. You would really need to explore the various OS and power
management settings as well as possibly some jCIFS settings.


A program should be written to  model the concepts of the task it
performs rather than the physical world or a process because this
maximizes the  potential for it  to be applied  to tasks that are
conceptually similar and, more  important, to tasks that have not
yet been conceived.
