When you open a webpage using Internet Explorer, Windows checks to see which security zone that page is assigned to and then applies restrictions to that page, based on the settings for that zone . Initially, any sites you connect to internally (that is, your own company's sites, which you access by means of an intranet connection) are automatically assigned to the Local Intranet zone, and if you choose to enable intranet settings the Local Intranet zone is accorded a Medium-Low level of security settings.
