This is the blurb..
“Monitor the status of up to 60 devices on your network or internet by pinging them and testing for a response with this Windows Desktop gadget. Various options available including variable ping timeout, option to display alert and play sound when devices go offline or come online, writing of log file and color scheme options.”
There is a version 3.1.3 in the Online Gadget Gallery, but you can get 4.0.1 from here..
I use it on my home network to see what is online. It would be particularly useful in a home network spread over multiple floors and/or rooms and for checking the status of a network printer BEFORE you send stuff and wonder why nothing is happening..
