title: Get List of all PSSessions for all users
body: <p>I am trying to connect with a remote PSSession to a server, but I am receiving the following error:</p>
  
  <blockquote>
    <p>The WS-Management service cannot process the request. The maximum
    number of concurrent shells allowed for this plugin has been exceeded.
    Retry the request later or raise the Maximum Shells per Plugin quota.
    For more information, see the about_Remote_Troubleshooting Help topic.</p>
  </blockquote>
  
  <p>I understand that I can increase the number of shells per user, but I would like to determine the cause of this error to alleviate it in the future. When I run a Get-PSSession -ComputerName "localhost" on the remote computer, no output is returned (implying my user does not have any sessions open). Is there a way for me to get all sessions for all users on the remote computer?</p>
