Fedor,

Thanks for your response!

I'll have to dig a little deeper to handle that one -- be back later
with an answer to that.

Yes!

Maybe, but I'm not sure how to check -- it is a Windows (Win95)
computer, it currently doesn't have enough hard disk space to load Linux
if I wanted to.

Is ICMP some new protocol?  In other words, can some machines respond to
pings without being able to handle ICMP?
