IIS does not start

[Utpal]

Hi everybody,
I installed IIS on Windows XP Professional and hosted my web application on it. It ran absolutely fine for a week (through Internet Explorer). However now when I try to run it from Internet Explorer using the url http://localhost/MyApplication/Default.aspx, it does not run and displays the error message "Cannot find server - The page you are looking for is currently unavailable...". When I go to Internet Information Services Manager and try to start the internet service, the error message "The service has not been started" shows up. What could be the problem? What is the solution?

Have a look in the event viewer - there should be a clearer message as to why it failed.
One of the common reasons is that another application has bound to port 80 - www.sysinternals.com has an application called "TCPView" that you can use to see if this is, indeed, the case.

The World Wide Web Publishing service was not running. On trying to start it the following error message showed up:
Error 3 - System cannot find the path specified. The same error message was present in the Event viewer.
There were no changes made to the system since it was last working.

There's probably another application bound to port 80 (received that error once when I had a port listener installed; it automatically bound to all open ports on start up).

TCPView can be used to confirm that.

But nothing was installed since the last time it was working.
