Hidden under the Tools menu in IE 6.0 is the Internet Options tool. Within the Internet Options dialog box is an extensive set of tools that affects how IE behaves relative to SharePoint sites. Although all the tabs in the Internet Options dialog box have extensive features, we will concentrate on just the Security and Advanced tabs in the section.
Figure 2.2 shows the Security tab within the Internet Options dialog box and the four Web content zones that IE uses to categorize different types of sites. You can add sites to any zone other than the Internet zone by highlighting the zone and clicking the Sites button, then typing in the address in the Add this Web site to the zone cell, and then clicking Add. Here are brief definitions of the zones:

For each zone, you have the ability to determine the settings within each site (unless the IT department has locked down the desktop so no changes can be made to IE). Clicking the Custom Level button brings up the Security Settings dialog box, as shown in Figure 2.3. If you scroll down to the bottom of the list, you'll see the User Authentication section, with several options available under the Logon heading. If Prompt for username and password is checked, every time a SharePoint site is accessed, the user will have to enter his or her username and password, which gets very annoying. Changing this to Automatic logon with current username and password typically avoids this problem.

Accessing the Advanced tab in the Internet Options dialog box provides access to many other custom configuration choices for IE, including Accessibility, Browsing, HTTP 1.1 settings, Microsoft VM, Multimedia, Printing, Search from the Address bar, and Security. In general, it is a good idea to stay away from the Advanced settings for IE 6.0 unless you have help desk support.
