Powershell 注销远程会话 [英] Powershell Log Off Remote Session

问题描述

我正在尝试制定一个 Powershell 命令来远程注销用户.我们有一个终端服务器，其程序非常不稳定，有时会锁定会话.我们必须远程注销用户，但我正在尝试编写一个 Powershell 语句，该语句将注销运行脚本的人.我搜索了一下，找到了这个命令:

I am trying to formulate a Powershell command to remotely log off a user. We have a terminal server with a very unstable program that sometimes locks sessions. We have to remotely log off a user but I'm trying to write a Powershell statement that will log off the person who ran the script. I Googled around, and found this command:

Invoke-Command -ComputerName MyServer -Command {shutdown -l}

但是，该命令返回不正确的功能".我可以成功运行括号内的其他命令，例如Get-Process.

However, the command returns "incorrect function." I can run other commands successfully in the brackets, such as Get-Process.

我的想法是将其放入一个脚本中，用户可以运行该脚本以从服务器注销(因为当它锁定时，他们无法访问开始菜单或 ALT+CTRL+END 以通过 GUI 执行此操作).

The idea is for me to put that into a script that users can run to log themselves off of the server (since when it locks, they cannot access the start menu or ALT+CTRL+END to do it through the GUI).

流程是这样的:Bob 通过 RDP 登录 MyServer，但他的会话冻结.在他的本地桌面上，他可以运行 MyScript(包含与上述类似的命令)，这将注销他在 MyServer 上的会话.

The flow would be this: Bob logs into MyServer via RDP but his session freezes. On his local desktop, he can run MyScript (containing a command similar to above) which will log off his session on MyServer.

推荐答案

也许令人惊讶的是，您可以使用 logoff 命令注销用户.

Perhaps surprisingly you can logoff users with the logoff command.

C:\> logoff /?
Terminates a session.

LOGOFF [sessionname | sessionid] [/SERVER:servername] [/V] [/VM]

  sessionname         The name of the session.
  sessionid           The ID of the session.
  /SERVER:servername  Specifies the Remote Desktop server containing the user
                      session to log off (default is current).
  /V                  Displays information about the actions performed.
  /VM                 Logs off a session on server or within virtual machine.
                      The unique ID of the session needs to be specified.

会话 ID 可以通过 qwinsta (query session) 或 quser (query user) 确定命令(请参阅此处):

The session ID can be determined with the qwinsta (query session) or quser (query user) commands (see here):

$server   = 'MyServer'
$username = $env:USERNAME

$session = ((quser /server:$server | ? { $_ -match $username }) -split ' +')[2]

logoff $session /server:$server
