Yes, I suppose it is a "phone edition" of windows mobile.

The info you provided was exactly what I've seen other places. Of course, I
know how to put in fully qualified network computer names, and that's what
I've been doing without success. The same qualified name that another
computer on the net can use to get to my computer (\\enpower\) when attempted
via the Open Path command only yields the error message:

The network path was not found.

and:

Network resource cannot be found or you do not have permission to access the
network.

The connection process never got far enough to ask for a username / password
(if needed) so I'm not sure what's happening.

Now, I've checked the firewall settings and everything is cool but, just in
case, I turned them all off without connection success.

Is there some other configuration point I need to modify? I'm currently
connecting via RNDIS. Switching to serial USB seems to make no difference
with the connectivity. I don't know if I need to change anything in the RNDIS
network connection to make the connection. I know my computer has several
sharepoints with relatively loose network access security.

FYI, I've been a computer consultant for over 20 years. I helped develop
OS/2 and NT device architecture and network protocols for Microsoft, IBM, and
several other OEMs. I worked for MSFT for 4 years as a consultant and as an
employee for 7 more years. Please feel free to send full technical data or a
technical manual to help me solve this problem.

Thanks!
