Mick,

Thanks for your time, but I just found the problem.  2Wire lists all the
devices that were ever connected to it by name, not by IP address.  I was
pointing port 5902 to a computer that has long been deceased and was
replaced by a new machine that inherited its name.  So 2Wire assigned a new
IP to the newcommer but still maintains both identical names in its list of
networked devices. I feel so dumb.
Thanks again.
Jean-Louis
