LazyTS is a PowerShell script to manage Sessions and Processes on local or remote machines. It allows you to Query/Disconnect/Stop session(s), Query/Stop process(es) and Send Interactive message to one or more sessions.

This tool is using the module PSTerminalService which relies on the Cassia .NET Library.I used Sapien PowerShell Studio 2014 to which make life easier if you want to start building WinForms tools and add PowerShell code.

  • PowerShell 3.0
  • Cassia Library (included in the download)

LazyTS is relying on the Cassia .NET Library (A DLL file). This file need to be present in the same directory as the script (Either when you use the PS1 or EXE file)

Of course you also need the appropriate permission on the remote machine to be able to manage it. If the Cassia.dll is not present, the script won't start:
