IIS 7.5 IP works but full name is not

Question

Here are the steps (Windows Server 2008, R2, IIS 7.5)

• create a new default virtual folder.
• create a new application in this virtual folder
• add helloworld.htm page to this application

• Access helloworld.htm without problems using the full name http: //server_name/virtual_folder/application/helloworld.htm

• for the application, change Security-> Authentication to require Windows authentication and not allow anonymous authentication

• in order to access the same page, you need to use ip_address instead of server_name.

Please, help!

Thanks PV
