Not an IIS config issue. It's a browser config issue. Add the address "intranet.company.net" to the Local Intranet security zone:
Internet Explorer May Prompt You for a Password http://support.microsoft.com/?id=258063 The following conditions must be met for Internet Explorer to automatically authenticate a user's logon and password and maintain security: * Internet Explorer must consider the requested URL to be on the intranet (local). If the computer name portion of the requested URL contains periods (such as http://www.microsoft.com and http://10.0.0.1), Internet Explorer assumes that the requested address exists on the Internet and does not pass any credentials automatically. Addresses without periods (such as http://webserver) are considered to be on the intranet (local); Internet Explorer passes credentials automatically. The only exception is addresses included in the Intranet zone in Internet Explorer.
