This is a handy new tool mainly aimed at support people like myself. The idea is that if you need to get someone to do a Network Monitor capture but they are not particularly familiar with Network Monitor they can just send them the link to this download, they download it, run it, it installs itself does a capture until they press a key on the keyboard at which point it stops capturing and then uninstalls itself. Voila! You have your capture.
Get it here.
