C# Signature:

     [DllImport("wtsapi32.dll", SetLastError = true)]
     static extern bool WTSDisconnectSession(IntPtr hServer, int sessionId, bool bWait);

VB Signature:

     <DllImport("wtsapi32.dll", SetLastError:=True)> _
     Private Shared Function WTSDisconnectSession(ByVal hServer As IntPtr, ByVal SessionId As Integer, ByVal bWait As Boolean) As Boolean
    End Function

User-Defined Types:

None.

Notes:

Note that you cannot disconnect the console session.

To indicate the current session, specify WTS_CURRENT_SESSION. To retrieve the identifiers of all sessions on a specified terminal server, use the WTSEnumerateSessions function.

To be able to disconnect another user's session, you need to have the Disconnect permission.

Tips & Tricks:

Please add some!

Sample Code:

    Friend Function DissconnectSession(ByVal ServerName As String, ByVal SessionID As Integer) As Boolean
    Dim RetVal As Boolean
    Dim ptrOpenedServer As IntPtr
    Try
        ptrOpenedServer = WTSOpenServer(ServerName)
        RetVal = WTSDisconnectSession(ptrOpenedServer, SessionID, False)

    Catch ex As Exception
        Throw New Exception(ex.Message & vbCrLf & System.Runtime.InteropServices.Marshal.GetLastWin32Error)
    Finally
        Try
        WTSCloseServer(ptrOpenedServer)
        Catch ex As Exception
        End Try
    End Try
    Return RetVal
    End Function
