IIS unexpected error?

[dzigner]

Hi
For my local websites, on iis 5.1, on win xp pro, nothing shows up in the browser - a blank page. In the IIS manager, there is an error beside the default website button. When I try to start it, it shows me the error:
Unexpected Error 0x8ffe2740 Occurred
In the http://support.microsoft.com/?id=816944, article for this error, they said another program is using the port 80, I changed the iis port to 85, the website started, but yet nothing on the browsers. I ran tcpview, and this is what I get for tcp ports:
See attached file
What is going on here? This used to work OK previously.
Thanks

Hi
Figured out which application was using port 80, removed the application and the IIS works fine now.
thanks
