ZEN WS Tools allows all of the functionality that is available from within NWAdmin including Remote Control and View, Ping, Workstation Diagnostics, Remote Execute, File Transfer and Chat. It also includes a choice for creating a short cut on the desktop that is associated with a single station. When you double click the short cut, a Remote Control session opens without running NWAdmin or ZEN WS Tools first! There is no help file and the only help in the program is a paragraph in the about box, but it is fairly simple to use.
