I have a Sharepoint 2010 web-site that I can access via a public ip address from any computer, except from the actual Sharepoint Server itself.
When I try to access the site from the Sharepoint 2010 server itself, I get prompted for the user and password. I enter it in and click ok, then it asks me again for the user and password with no error message. I tried entering it again and it just keeps prompting me for the user name and password.
I have tried IE and Firefox and they both do the same thing.
