我要评论重点: 
单单的防还是不能解决问题，下面是我们找出真凶了
给大家介绍一个工具可以像mmc计算机管理管理单元中的“会话”文件夹，显示的是通过网络登录到计算机的会话，
远程服务管理单元显示的是远程桌面登录的会话，但没有一个工具可以显示所有登录会话---不管任何登录类型--以及这些用户使用的程序列表。
这个工具是sysinternals（现在已经是微软）的logosessions工具!
http://www.microsoft.com/technet/sysinternals/security/logonsessions.mspx
可以从这个地址去下载 free
可以把logosessions中显示代码和其它工具显示的信息关联起来。
复制代码
代码如下:日志

==============================
在安全日志事件中，可以把输出的登录会话id和安全日志事件说明进行关联，查找登录事件和会话相关的事件。
这样很容易找到是怎么回事了....
