Skype behind IIS error

I got a problem with Microsoft Internet Information Services (IIS) and the Default Web Site. I found out that Skype was taking up port 80. The error message "Unexpected error 0x8ffe2740 occurred." was not obvious and the System Event showed below neither.

Event Type: Error
Event Source: W3SVC
Event ID: 115
Description:
The service could not bind instance 1. The data is the error code.

Solution to this problem. In Skype>Options>Connections uncheck this option "Use port 80 and 443 as alternatives for incoming connections" or temporary stop Skype, start the Default Web Site and after that Skype.
