[Quick Fix] ASP.Net Load Problem

If you are having trouble loading your ASP.Net sites from the IDE and you have IIS Manager installed, you need to open up the IIS Control Panel

IIS Manager Control Panel -> Authentication -> Disable ASP.Net Impersonation

IIS = Internet Information Services (Pre-installed on Windows 7)

To get to the IIS quickly, hold Windows Key + R, then type inetmgr

(I have become very familiar with the built in IIS because of work.)
