AlertPing allows you to ping a number of hosts and display their current status (online/offline). The program can operate on a timer, e.g. ping a server every 5 minutes and also send an alert via LAN, run a program or or send an email if a server is down/up. In addition, you can setup a sound notification or have the program pop-up a message box. AlertPing can run in the system tray and will indicate problems by a color changing icon. Small and easy to use.
