I'm trying to locate the mac address using a utility called networkview. The machines are on the netowork and have an IP address of the specific vlan. I cannot ping the ip address it says request timed out. Do you think the machines have some type of software that are making them unpingable and unseeable. What can I do to see the IP or mac address. I have written them down but it would be nice if I can use some utility to see these machines.
