When you use the TSDICON command to disconnect an active Terminal Services session, the session remains attached to the Terminal Services server, but in a disconnected state. Programs that were running remain running. You can subsequently reconnect to the same session and resume work without loss of data in the running programs.
When you type tsdiscon /?, you receive:
Disconnects a terminal session. TSDISCON \[sessionid | sessionname\] \[/SERVER:servername\] \[/V\] sessionid The ID of the session. sessionname The name of the session. /SERVER:servername Specifies the Terminal server (default is current). /V Displays information about the actions performed.NOTE: You cannot disconnect the console session.
NOTE: To disconnect another user's session, Full Control permission is required.
Example:To disconnect a session on the current Terminal Services server:
1. Open a CMD prompt.
2. Type query session. You will receive a display like:
SESSIONNAME USERNAME ID STATE TYPE DEVICE console administrator 0 active wdcon rdp-tcp 65536 listen rdpwd >rdp-tcp#1 user1 1 active rdpwd rdp-tcp#2 user1 2 active rdpwd rdp-tcp#3 user2 3 active rdpwd rdp-tcp#4 user3 4 disc rdpwd rdp-tcp#5 user1 5 active rdpwd 6 idle 7 idlewhere rdp-tcp#1 is the current session, session ID 1, owned by user1.
3. To disconnect the current session, type tsdiscon. To disconnect session ID 2, type tsdiscon 2 /v, which will display Disconnecting sessionID 2 from sessionname rdp-tcp#2. To disconnection rdp-tcp#5, type tsdiscon rdp-tcp#5.
