I get no response as if the server (dns) doesn't exist. I can't
ping or tracert as NetworkAdmin disabled both. I have a strong

Thanks.
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...

Maybe the traffic is getting in through your firewall, but not
making it back out to the clients.
