Syntax

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

Parameters

Parameter Description
/query Displays the current logon status, whether enabled or disabled.
/enable Enables logons from client sessions, but not from the console.
/disable Disables subsequent logons from client sessions, but not from the console. Does not affect currently logged on users.
/drain Disables logons from new client sessions, but allows reconnections to existing sessions.
/drainuntilrestart Disables logons from new client sessions until the computer is restarted, but allows reconnections to existing sessions.

Remarks

  • Logons are re-enabled when you restart the system.

  • If you're connected to the Remote Desktop Session Host server from a client session, and then you disable logons and log off before re-enabling logons, you won't be able to reconnect to your session. To re-enable logons from client sessions, log on at the console.

    change logon /query

  • To enable logons from client sessions, type:

    change logon /enable
