check_external_commands option - host showing down when it's up

Well, I've troubleshot it down to where the problem is
lying, now it's just a matter of seeing if it's the
host that really does have a problem. Basically,
Nagios is complaining that the TTL is being exceeded
for this host, yet I have another host in the same
office with the same conditions that doesn't get
anything like that. So I'm just confused how this came
up all of a sudden. Since the second host is just
fine, I thought Nagios might have been having some
kind of issue. I think I'm going to be troubleshooting
more on the server side now as opposed to thinking
that Nagios is having any problems. Thanks for your
help, much appreciated as always.
