I had the same problem, and i fixed this way:
Go to IIS Manager -> Go to the site -> Error Pages -> Actions: edit feature settings.. -> Make sure you checked "detailed errors for local requests and custom error pages for remote requests".
IF you are using IIS6 and did the add mapping for .* in IIS trick to get MVC working, when you added the .* handler to iisapi.dll you forgot to uncheck the "check the file exists" check box.
The root cause for this error can often be that the Windows Service W3SVC is not started. Check that this service in Windows Services console (services.msc) is started. In IIS you will now see the the Start icon is greyed out. This means that the W3SVC service is running.
What i did, was just type the IP address in the web tab instead of "localhost"
