This module allows you to get information about Remote Desktop and Console logon sessions on Windows machines, and to enable you to disconnect users from them and/or log them off.

• The PSTerminalServices PowerShell Module (https://psterminalservices.codeplex.com/)
• PowerShell Remoting (to get the time that a session was locked at the console)

Import-Module LogonSession
Get-LogonSession -ComputerName [comp]

Returns a collection of PowerShell objects which are a slightly modified version of the types that you get from the PSTerminalServices module's Get-TSSession function. You can then look at information about them, or call the Disconnect() or Logoff()/Logout() functions to forcibly disconnect or log off the user.
