ASP pages in IIS using Localhost 401.3 Error do not have permission

Question

I have just installed the IIS so I can view asp files in a browser but when I put the address in a browser as : http://localhost/index.asp I get an error.

The error

Answer 1

I had one folder not working (extracted from a zip file which came from an email from some kind of MS Sharepointy thing. Or something). The files were all marked with Windows Explorer -> Right Click -> Properties -> Advanced -> Encrypt contents to secure data. Unticking cured it.
