SUMMARY描述
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
发生未知错误0x8ffe2740

CAUSE原因
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.
这个错误可能由于系统端口冲突造成。IIS默认使用80端口,如果另外一个程序在同一IP地址上使用了80端口,您可能会收到这个错误提示。

RESOLUTION解决方法
• 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.

• 在IIS管理器中,改变站点邦定端口,使用80以外的端口。
• 停止正在使用80端口的程序,再启动IIS站点。
