I have a sharepoint site hosted on windows server 2008 r2 and iis7.
the sharepoint site is hosted on port 80.
when I browse the site by typing the IP of the machine I receive a login window asking for credentials to connect the Machine. after providing credentials another login window asks for credentials to connect to the sharepoint site.
my question is that when a user logs in to a sharepoint site he uses the credentials specified in the active directory, so why in my case I recieve the login window twice ?
