Question

I have a website setup to use two different bindings in iis. When visiting one url windows authentication works, but when using the other url it prompts the user for their login credentials (and doesn’t work)

Any ideas what’s going on here?

Answer 1

Could be a whole plethora of things:

• ACL permissions on the files/folder themselves.
• Impersonation on in one app and not another.
• IIS security settings allowing anonymous on one and integrated on the other with improper permissions, etc etc.

Check permissions are the same, web.config settings are the same for authentication, and IIS security settings are the same and that the user you are trying has permissions to the files/folders.
