I am using Bysoft StayAlive Pro, a small tool that keeps my internet connetion alive by querying random web pages every 60 seconds. It is a little system tray application that runs in the background. It works quite well.
I'm looking for something that functionally is the same as BySoft StayAlive Pro... but runs as a service, not as an EXE. This is because my machine is running Server 2003, a user is not necessarily going to be logged in all the time.
