“Unable to launch the IIS Express Web server” error

Question

I receive this error when trying to launch IIS Express from Visual Studio with a project that\'s configured to listen to an address other than localhost. Visual Studio free

Answer 1

I was changing this entry (for which my web server was not running and showing me access denied error for a particular port)

<bindings>
   <binding protocol="http" bindingInformation="*:61235:localhost" />
</bindings>

in the "applicationhost.config" in "Documents\IISExpress\config" for a particular webapplication it was overwritten by Visual Studio 2012 again to default port whenever I was starting my webapplication.

But I resolved the problem by doing nothing in the applicationhost.config. I just changed the "project properties" > "web" > "project url" setting from http://localhost:62135/ to http://localhost:47279/(depends on your computer) and it worked for me.
