I have a Windows system which is able to do the traceroute - but maybe it is
What I am trying to solve is actually a bit more than just getting
traceroute to work. I am trying to use sendmail/mail to send mail to a mail
server. The mail's are not getting through though. A look at the mailq
indicates it is because there was no route to the host. And yet I can ping
the host. So I though if I can sovle the traceroute problem, I can solve the
mail problem. Another clue is that I can successfully send mail to my
"local" mail server.
Any ideas why the route to host cannot be found?
