I am attempting to logoff a remote user using wmi via vb.net. I created the below code in the wmi code creator but it doesn't do anything  it doesn't even error out:

Dim scope As New ManagementScope( _
                "\\192.168.1.105\root\CIMV2")
            scope.Connect()

            Dim classInstance As New ManagementObject(scope, _
                New ManagementPath("Win32_OperatingSystem.ReplaceKeyPropery='ReplaceKeyPropertyValue'"), _
                Nothing)

            ' Obtain [in] parameters for the method
            Dim inParams As ManagementBaseObject = _
                classInstance.GetMethodParameters("Win32Shutdown_OperatingSystem")

            ' Add the input parameters.
            inParams("Flags") = 0

            ' Execute the method and obtain the return values.
            Dim outParams As ManagementBaseObject = _
                classInstance.InvokeMethod("Win32Shutdown_OperatingSystem", inParams, Nothing)

Open in new window

Is WMI a requirement? If not, you can use following

System.Diagnostics.Process.Start("shutdown.exe", String.Format(@"/l /f /m \\{1}", remoteComputerName));

Sorry that was C#. Try

System.Diagnostics.Process.Start("shutdown.exe", String.Format("/l /f /m \\{1}", remoteComputerName))

String.Format arguments are 0-based:

System.Diagnostics.Process.Start("shutdown.exe", String.Format("/l /f /m \\{0}", remoteComputerName))

I haven't used the Shutdown command to log off a remote user, but I would have thought that it could work.

Shutdown
http://technet.microsoft.com/en-us/library/bb491003.aspx

-l   : Logs off the current user, this is also the default. -m ComputerName takes precedence.
-m [ \\ ComputerName ] : Specifies the computer that you want to shut down.

You can't use -l and -m together, since -m takes precedence over -l.

It looks like Win32_OperatingSystem.Win32Shutdown method has that capability to log off a user:

Thanks for the info, i saw that on google searches and couldnt figure out how to make it for remote use, it looks like its local only the way its written.  Im using psexec now, i open a CMD window locally into the remote user, query session and then logoff the users ID...  That will work for me.
