IIS failed to start: cause of unexpected error 0x8ffe2740

This morning, I found that IIS failed to start, error: Unexpected errors 0x8ffe2740.

Then there is a red "Error" on IIS.

Go to the Internet to check the relevant information, exclusively reply:

Solving method

To work around this problem, you can do any of the following:

• Change the site binding port in IIS Manager to a port other than the 80 port.

• Stop the application that is using port 80 and start the Web site from IIS Manager.

More information

You can use third-party tools such as TCPView or FPort to determine other applications that are using port 80.

At first I thought it was a problem with IIS, but it was repeated several times, the problem is still ....

During the detour, the Oracle unloaded and loaded, loaded and unloaded, the whole of the almost 10 times, I was about to collapse, we all know that Oracle unloading once again to one hours to install. >_<~~

Later, I used TCPView to find out that one of the services in Oracle that was installed yesterday was 80 ports old.

But can not unload Oracle, how to do??

After a long deliberation, the solution is:

First stop the services in Oracle, then start IIS, and then start the Oracle service.
