Given the facts. Any other ideas? Is there something that I should be trying.

If Apache has nothing in the error log and nothing in the access log, and it works sometimes
but not other times, then it's not Apache.  There's something wrong with your network, firewall
or DNS.

If your network administrator has disabled ping and traceroute, then he's a bonehead.  How
can you adminster a network with the primary diagnostic tool disabled?  Some admins think
(incorrectly) that disabling ping somehow makes the network more secure.  They need to go
back to school.

But that's a topic for a different forum...

what do you mean? Do you get no response at all, as though the server doesn't exist? Do you
get an immediate "refused connection" message? What exactly is happening?
