The IIS site cannot be started, and the World wide Web Hing service cannot be started!

Patch 360 was used a few days ago, and later I found that the IIS network could not be started. As a result, I found that the IIS Admin Service was enabled,
The reason should be that the WEB publishing Service is not enabled. When the World wide Web Hing is enabled,
Tip: ERROR: 127 ERROR. The process cannot be found. Then I went to the MS website and checked it out because of the security patch,
Security Update for Windows XP (B939373)
You have installed an XP patch, which prevents IIS from being started.
Solution
Go to "Control Panel"-> "Add/delete programs"-> click "display Update" at the top of the page-> Find "windows xp software update"
-> Uninstall "KB939373" and then start IIS. If you want to use IIS, skip this patch,
I can start IIS at last, but I am not happy yet. I did not expect that there was a red ERROR icon before the Default Web Site.
I have encountered this problem before,
Roar ....
The reason is that port 80 is occupied by other programs.
Solution: Of course, the terminal number is changed. Right-click the Default Web Site and select "Properties" to change the Default port number, for example, 8080,
After IISRESET is restarted, the access address is changed to http: // localhost: 8080/MyWebApplicatoin.
You must specify the port number.
Of course, you can use a command to check which process occupies port 80.
Netstat-an-p tcp can list all TCP port numbers, find port 80 in the Local Address column, and find the corresponding PID.
After obtaining the PID, you can view the process name in the task manager. By default, the task manager does not display the PID column.
Select View> Select Columns... Select the "PID" column.
