某用户报障说除了内网，无法打开外网的网页。细查之，发现本地连接处有个Microsoft TV/Video Connection，咦 ？什么东东？我最担心的是由于启用了两个连接，例如有线与无线，引致问题，所以试着想将其停掉，测试下，却显示无法停止，设备正在使用中。通过设代理，设固定IP方式均无法解决。最后尝试用winsockfix解决掉了。
后来上网查了下Microsoft TV/Video Connection。
参考Microsoft官方文档
SYMPTOMS
After you add a universal serial bus (USB) camera or a TV tuner card to a Microsoft Windows XP-based computer, a Local Area Connection 2 icon may be created in the View Network Connections section in My Network Places. The information that is displayed below this icon describes the connection as:
Microsoft TV/Video Connection
WORKAROUND
To work around this behavior, restart the computer. After you restart your computer, the Local Area Connection 2 icon does not appear.
