Change logon

Enables or disables logons from client sessions, or displays current logon status. This utility is useful for system maintenance.


change logon {/enable | /disable | /query}

  • /enable
    Enables logons from client sessions, but not from the console.
  • /disable
    Disables subsequent logons from client sessions, but not from the console. Currently logged on users are not affected.
  • /query
    Displays the current logon status, whether enabled or disabled.
  • /?
    Displays help at the command prompt.
  • Only administrators can use the change logon command.

  • Logons are re-enabled when you restart the system. If you are connected to the terminal 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.


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:
