HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers

i want to allow access to Anonymous.aspx page to all user, i have set Basic Authentication to Enabled, and Connect as to specific user.

my problem is when trying to access http://MyIPAddress/MyAlias/Anonymous.aspx, authentication popup appears--ideally it shouldn't, and when i close popup, getting 401.2 Unauthorized error--it's obvious

Error Summary

HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers. Error Code 0x80070005

below is snap of my web.config file.

<configuration>
   <system.web>
       <authentication mode=“Windows“/>
   </system.web>

   <location path=“Anonymous.aspx“>
       <system.web>
          <authorization>
              <allow users=“*“/>
          </authorization>
       </system.web>
   </location>
 </configuration>

how can i solve this error.

Make sure Anonymous access is enabled on IIS -> Authentication.

But also right click on it, then click on Edit, and choose a domain\username and password. (With access to the physical folder of the application).
