Check Network

- Copyright © 2018-2020 by Mark Mellor

This program monitors the network connection of a computer. If the network connection is lost then the user is informed via a status textbox and optional sound (WAV file) and/or background color change. The user can also receive an email when the network connection is restored. Another option is to receive a hourly email informing the user that the network connection is working. The network connection is checked every 60 seconds. It is recommended to test the email after entering the email settings. There are two tabs in the email settings section. One for the email if network connection is restored and the other for the hourly email. There is an option to send commands out a COM port if the network connection is lost. Normal operation just checks if the computer is connected to a network. The computer could be connected to a LAN but not have internet access. The program would report that the network connection is working. If you want to check internet access or you just want to monitor a remote computer then use the ping option (Other Settings → Ping Computer). This program can prevent the task manager from closing the program and can prevent the computer from going to sleep. There is a log file. There is one command line argument: autostart. This will start the network connection monitoring immediatly.
