Internet Explorer 7 incorrectly recognizes an intranet Web site as an Internet Web site

When you visit an intranet Web site, Windows Internet Explorer 7 incorrectly recognizes the Web site as an Internet Web site. Therefore, if the Web site requires user authentication, you are prompted to enter the user account in the domain and to enter the corresponding password. You expect Internet Explorer to automatically send user authentication information to the domain when you visit an intranet Web site.

This problem occurs if you configure Internet Explorer 7 to use an automatic configuration script.

Notes

• In Windows Vista, this problem does not occur when the User Account Control (UAC) feature is enabled.
• This problem does not occur if you visit an intranet Web site by clicking a link in a Web page.
