设定系统网卡各种参数，如ip,dns,相关参数。在2000下立即改变网卡参数。-card system set various parameters, such as ip, dns, the relevant parameters. In 2000 card immediately change parameters.

可以清晰了解TCP/IP，UPD协议中，每个包所包含数据的含义等，包括每一帧数据的头，校验等，解码的数据让你清晰了解底层通讯的机制。非常珍贵。

在WINDOWS下进行网络服务端程序开发，毫无疑问，Winsock 完成端口模型是最高效的。Winsock的完成端口模型借助Widnows的重叠IO和完成端口来实现，完成端口模型懂了之后是比较简单的，但是要想掌握Winsock完成端口模型，需要对WINDOWS下的线程、线程同步，Winsock API以及WINDOWS IO机制有一定的了解。如果不了解，推荐几本书：《Inside Windows 2000，《WINDOWS核心编程》，《WIN32多线程程序设计》、《WINDOWS网络编程技术》。在去年，我在C语言下用完成端口模型写了一个WEBSERVER，前些天，我决定用C++重写这个WEBSERVER，给这个WEBSERVER增加了一些功能，并改进完成端口操作方法，比如采用AcceptEx来代替accept和使用LOOKASIDE LIST来管理内存，使得WEBSERVER的性能有了比较大的提高。 -under the Windows network server program development, no doubt, Winsock completed port model is the most efficient. Winsock port model with complete preview of overlap and complete port IO to achieve complete port after the model to understand is a relatively simple, but want to know the complete Winsock port model, the need for the Windows threads, thread synchronization, Winsock API and Windows IO mechanism of a certain understanding. If we do not understand, recommended several books : "Inside Windows 2000," Windows core programming "," WIN32 multithreaded program
