The service could not bind instance 1
In work this morning I attempted to fire up Visual Studio with an ASP.NET application I hadn’t used in a while only to receive an error message stating that the project could not be mapped to an IIS application. Looking deeper I found that the application did indeed exist, but IIS was not behaving nicely – a big STOP sign replacing my normally very pleasant default web site icon. The Event Viewer should the following error:
A little trial and error and I found the issue and simple solution. Port 80, used by IIS was also being used by Apache which I had recently installed on my local box. Shutting down Apache allowed IIS to restart correctly, and from there I could (if I so chose) change the default port on Apache thereby permanently fixing this issue. Simple!
Event Type: Error
