1、问题描述

　　通过Eclipse启动tomcat报错：Several ports (8005, 8080, 8009) required by Tomcat v7.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s)，按照网上的解决办法改端口也没有用（通过netstat -ano根本就没有发现端口被占用）。

2、解决办法

查看logs里的日志发现启动报错了：

java.net.SocketException: Unrecognized Windows Sockets error: 10106: create
	at java.net.ServerSocket.createImpl(ServerSocket.java:308)
	at java.net.ServerSocket.getImpl(ServerSocket.java:257)
	at java.net.ServerSocket.bind(ServerSocket.java:376)

	at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:493)

3、操作步骤

　　打开cmd，输入：netsh winsock reset 然后回车

　winsock是Windows网络编程接口，winsock工作在应用层，它提供与底层传输协议无关的高层数据传输编程接口 netsh winsock reset 是把它恢复到默认状态
