Would anybody happen to know of a simple utility to monitor a network? I'm looking for something that lets me create a map with icons that ping devices and change from green to red depending on successful ping. I need to be able to layout the icons to represent their relative physical location. Nothing to complicated, I don't need SNMP or Services monitoring. I have to set it up to monitor a network with 50+ devices and hand it over to a group of people who are somewhat "network challenged". Thanks!
