上古卷轴5翅膀铠甲mod:IIS问题，XP专业版，装好IIS组件，默认网站自动停止

SUMMARY
When you try to use Internet Information Services Manager (IIS Manager) to start a Web site, the Web site does not start, and you may receive the following error message:
Unexpected error 0x8ffe2740 occurred

CAUSE
This behavior may occur if a port conflict exists on the system. By default, IIS uses port 80 for HTTP communication. If an application other than IIS is running and is using port 80 on the same IP address, you may receive the error message when you try to use IIS Manager to start the Web site.

RESOLUTION
To resolve this problem, you can do either of the following: • In IIS Manager, change the port bindings for the Web site to a port other than port 80.
• Stop the application that is using port 80, and then start the Web site from IIS Manager.

大致含义为：IIS Web site默认使用80端口，若在启用IIS Web site时其他程序在同一IP地址上占用了80端口，你就会收到这条错误

这种情况是80端口被其它的程序占用了。把默认网站的端口改为其它端口。（比如8080等），找出其它占用了80端口的程序，释放出80端口，再把默认网站的端口设置为80就行了。
