I have an ASP.NET application running on Windows Server 2012 R2, IIS 6.2.
Under IIS I set in the authentication Anonymous Authorization to Disabled and Windows Authentication to Enabled.
On the client machine IE settings: Added the site's domain to trusted sites, set to medium-low security in this site and enabled automatic logon.
It still prompts client to login with a popup window. I thought it should just automatically send the client credentials. (Client machine and server (IIS) machine It is same domain as well). Is it something missing? Am I doing something wrong? I am expecting it not to prompt for login, since user is already logged in to the domain. It should just send credentials of machine right?
