Tip: Unexpected error 0x8ffe2740 occurred while starting IIS web site

Occasionaly, it might happen that when you start your IIS web site, an unexpected error occurs - see image in attach.

In this specific case, another application in your system (e.g. Skype, etc.) might be using port 80 which doesn't allow IIS to start. Do a TCP port trace using an utility (netstat Windows system command is good enough: netstat -a -b) and find which application is the cause. Close it, then start IIS again.
