Microsoft's IIS 5.0 web server is shipped with a set of
sample files to demonstrate different features of the ASP
language. One of these sample files allows a remote user to
view the source of any file in the web root with the extension

If for some reason this is not possible, removing the following ASP script will
fix the problem: 
        
This path assumes that you installed IIS in c:\inetpub
        
c:\inetpub\iissamples\sdk\asp\docs\CodeBrws.asp
