Need to log a User off of a Continuum Workstation from a remote Cyberstation.
No documented solution on how to log off a remote Workstation.
If you know the name of the User that is currently logged on, you can open that User object from another Workstation and disable the user. This will immediately log that user off of their current session in Continuum and lock them out of the system until their User object is re-enabled.
To determine the name of the User, you can use the solution in Is there a way to determine who is actively logged into CyberStation and onto which workstation? to determine what users are currently logged on to Continuum using the Activity Log.
