Windows has another bug; they don't include a proper loopback function
with the standard distribution _and_ they have some asenine view that if
there's no physical network connection available, they tear down the
network stack! This means that anything that connects with TCP/IP can't
work, even if it's to the local machine. I consider this idiocy, but,
there's windows for you in a nutshell...

However, you _can_ find a proper "loopback driver", I think they call it -
software, of course. Also, I carry in my laptop case a special HARDWARE
loopback connector! It's an RJ45 that has the wires crossed over. I use it
when I'm at a customer site or otherwise "away from home" and my customer
doesn't have the software loopback - plug my loopback connector into any
"twisted pair ethernet" socket and suddenly the TCP/IP software works
fine!

Oh the joys of dealing with Windows.

P.S. You can't get one of these RJ45 loopback connectors commercially, I
don't think, but I can send you directions - or make one for you if you
send me a tenner! -smile-  RT
