AlertPing Description:

While your hosts are hanging-up,your income is falling. Stop it with "AlertPing"!
Alert Ping verifies accessibility of your host computers!
It is used for 'pinging' IPs, f.e. computers in your local area network or in the internet.
Build a list of TCP/IP devices (computers, printers, and other network components) to verify their network connections. AlertPing periodically pings each device to determine its network connectivity. After issuing a ping request, the program waits for a reply, if AlertPing receives a failed ping request, different alarm and alert messages can be sent. The program runs as a minimized system tray icon.
