Remarks

  • Only administrators can use the change logon command.

  • Logons are re-enabled when you restart the system. If you are connected to the Remote Desktop Session Host (RD Session Host) server from a client session and disable logons, and then log off before re-enabling logons, you will not be able to reconnect to your session. To re-enable logons from client sessions, log on at the console.

Examples

  • To display the current logon status, type:

    change logon /query
    
  • To enable logons from client sessions, type:

    change logon /enable
    
  • To disable client logons, type:
