WatchDog is an application that can run on any networked computer. It attempts to Ping a particular computer, either by name or by TCP/IP address. While communications are working effectively, WatchDog will just sit quietly with a small icon in the system tray The main form also shows the current status in the same way When a network error occurs, the remote server is taken off the network, or powered down, the WatchDog application then takes life! The icon in the system tray shows an error has occurred , which is also shown on the form But more importantly, WatchDog can now execute another application.This could be any of the following: Send an email Activate a pager Send a network message Cause software running on the local machine to stop Switch networks Switch remote servers Anything that can be done from a command line! If the local machine isn't being monitored - say it's in a remote room, or in a rack mounted cabinet, then the error message can also be turned off - as there will be no-one to see it!The Ping time is defined Options: Obviously, the name (or TCP/IP address) of the remote machine is changable, however, so are the following: Ping Time Display Timeout Message Command line to execute How the executed command line is shown (Hidden, Maximised, Normal, etc)
