This is an issue with binding conflict. There is another application that is using port 80. If you change the bindings for the default website to 8080 [for test purpose] it will work.
You can run NETSTAT -ano and find out the PID for the process that is using port 80, then you can compare that PID with the process name in task manager [may be skype.exe?]
