Tips & Tricks:

For the server handle (first parameter), please use WTS_CURRENT_SERVER_HANDLE if the code is running on the same machine whose handle you intend to pass. Otherwise, use WTSOpenServer as shown in the sample code.

Sample Code:

    Friend Function LogoffSession(ByVal ServerName As String, ByVal SessionID As Integer) As Boolean
    Dim RetVal As Boolean
    Dim ptrOpenedServer As IntPtr
    Try
        ptrOpenedServer = WTSOpenServer(ServerName)
        If WTSLogoffSession(ptrOpenedServer, SessionID, False) <> 0 Then
        RetVal = True
        End If
    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
