I am using some web hosting provider (Windows, IIS, ASP.NET). My site worked good. One day I got an error "You are not authorized to view this page. HTTP Error 401.3 - Unauthorized: Access is denied due to an ACL set on the requested resource." when I tried just access my site. So I had to input login and password to access my home page.
Has anyone ever got so error? I am appreciated to get any help.
Configuration: Windows 2003 Server Enterprise IIS 6.0
