nginx An attempt was made to access a socket in a way forbidden by its access permissions

在安装了 sqlserver 的win7 与 win 上启动 nginx，绑定80端口，报错：

nginx An attempt was made to access a socket in a way forbidden by its access permissions

查了百度，说修改注册表，但我的电脑上找不到文中说的注册表值。

后来发现，原来是sqlserver 的sqlserverreportingservices 使用 80端口。进入服务，关闭它。
