Even default ASPNET websites seem to require Windows Authentication enabled on my machine when Anonymous Authentication should do, what could be wrong with my IIS7/ASP.NET install?
I’ve ran aspnet_regiis /i but it still does not not fix it!
I get 401.3
Access is denied.
Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources.
Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the Web server’s administrator to give you access.
It looks like the issue is with Basic Authentication being disabled, by default.
Enabling this fixes the issue!
