[olug] Networking problems

[Don Kauffman]

I'm writing this from my M$ box!  I'm not sure what happened. I shutdown both
machines last night as I normally do. This morning I "woke 'em up" and had
another stab at trying the ping from the M$ box. I went through the steps that
Brian W. suggested and they all worked! Then I was able to get mail on M$ box.
This is another head scratcher for you! Gotta admit, it's kind of a nice one
but I'm a little concerned about why it's working now and wasn't last night.
I'd like to get a little firmer grasp on what I did that made it work and not
work.

Thanks Gang! I really appreciate the help!
