The title kind of says it, but I'll describe the situation. I have Linux box (Ubuntu 9.10) running Apache2, PHP and Mysql to serve Joomla. The IP is 192.168.10.12 and the hostname is Exia. Other Linux machines on the network, as well as Windows XP boxes with ESS can get to it and ping it just fine. Vista, for whatever reason, can't. Attempting to ping it causes a timeout, the same for trying to browse to it. As soon as the firewall is disable, though? It goes through. The Vista machines can ping a Linux box without Apache/etc normally. I'm not sure if Windows 7 will do the same thing, but I'm about to test it. Any ideas why this is happening and how to fix it? EDIT: Same thing with 7.
