I have a strong feeling that it is firewalls but our NetAdmin thinks otherwise. -- 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...

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 feeling that it is firewalls but our NetAdmin thinks otherwise. -- Thanks.
