I've run into this issue on various Windows Servers: When logged into the server, IIS Windows authentication through a browser does not work for either Windows Auth or Basic Auth.
I have several sites set up with Windows authentication, and when I try to access them from the server I cannot log in. Not with just username or password, or domain+username/password.
However, accessing the same site externally and logging in works just fine, using my Windows log on credentials.
So - why can I not log in locally in this case?
- Server is not on a domain (single box)
- Using Chrome, but also tried with IE on the server same result
- Access via RDP, using an admin account
- IIS Basic Authentication fails the same way for application tasks
