I would be VERY interested in your feedback about what we could
do to make the manual better for NT users.  Please contact me
directly at 'dyork@e-smith.com'.  Thanks.

Maybe... maybe not.  If you can't ping, there's a lower level
issue of connectivity that is not occurring here. On your NT box,
if you do:
  ipconfig
do you see an Ethernet adapter with an IP address of 192.168.1.x?
Next, if you do (on your NT box):
  route print
do you see something along the lines of:
  192.168.1.0  255.255.255.0  192.168.1.x  192.168.1.x  1
that would be the route you should see.  If you do not, then something is not getting set right at an IP level.
You should also see a default route that looks like:
  0.0.0.0   0.0.0.0   192.168.1.1  192.168.1.x  1
If these routes *are* there and are okay, there's some other issue we need to look at.
