Sorry. I assumed they all behaved the same way. I have only tested it on
NT and 2K.

A service on any machine is an IP:SOCKET combination. If you have setup
your local machine to be the source end of a tunnel for any port, then
that service cannot be made available on the local machine too because
both have the 127.0.0.1:"XXX" combination. So essentially, if you create
an alias for your loopback adapter by adding an MS-Loopback device to the
tcp protocol stack but with a different address, you can tunnel the
ALIAS:SOCKET combination and still have local access to the
LOCALHOST:SOCKET combination.

I have a "xxxxxxxxx" running on my laptop and the same thing running
on my server. When I do development work on the laptop I just point to
127.0.0.1 and when I want to use "production" on the server at the end of
the tunnel I use the alias address.

Enjoy,
