8. You may also get this error if you have opened a website (not using a solution) that was developed for in VS2010 framework 4.0 with VS2008 on windows XP. In this scenario the app is using XP’s webserver rather than VS2010’s built in webserver.

17. Just go to Control Panel > Programs and Features > Turn Windows features on or off > Check Internet Information Services
