Recreational Software Advisory Council on the Internet (RSACi). The most common use for Content Advisor is on a home computer on which parents want to control the Web sites that their children can view. You can control access based on language, nudity, sex, and violence. Ratings for Web sites are based on voluntary ratings by Web site creators. However, by default, Content Advisor does not allow you to open sites that have not been rated. You can also create a list of Web sites that are always viewable or never viewable, no matter how they are rated.

The Connections tab of the Internet Options dialog box, shown in Figure 16-18, allows you to control how Internet Explorer connects to the Internet. If the computer uses a dial-up or virtual private network (VPN) connection to connect to the Internet, those connections are shown in the Dial-Up And Virtual Private Network Settings section. Click Add to start the New Connection Wizard, which you use to configure networking connections (and which you learn more about in 15, Configuring Network and Internet Connections ). When you select one of the displayed connections, you can also configure the following options for that connection: Never Dial A Connection Requires that you manually establish a connection before opening Internet Explorer. Dial Whenever A Network Connection Is Not Present Causes Internet Explorer to use the current default connection if it detects that there is no existing connection to the Internet. Always Dial My Default Connection current default connection. Causes Internet Explorer to always dial the

To configure the default connection, select a connection from the list and click Set Default. You can also use the Connections tab to configure proxy server settings. A proxy server is a centralized network device that provides Internet access to the client computers on the network, as shown in Figure 16-19. Proxy servers are used to centralize Internet connection settings, increase security by controlling which resources a client can access, and speed up Internet access by caching Web pages to the server. After you configure Internet Explorer to use a proxy server, Internet Explorer requests Internet content from the proxy server, which in turn connects to the actual Internet resource on the client s behalf, retrieves the information, and forwards it to the client.

To configure Internet Explorer to use a proxy server for dial-up and VPN connections, select the connection, and then click Settings. To configure Internet Explorer to use a proxy server for local area network (LAN) connections, click LAN Settings. Figure 16-20 shows the available proxy server configuration options, which are as follows: Automatically Detect Settings Allows the client to automatically receive proxy server configuration from a properly configured Dynamic Host Configuration Protocol (DHCP) or Domain Name System (DNS) server. Use Automatic Configuration Script Specifies the path to a configuration script containing proxy server information. Use A Proxy Server For This Connection Allows you to enter the address of the proxy server and the port that Internet Explorer should use to connect to the proxy server. Bypass Proxy Server For Local Addresses Allows the client to connect directly to address on the local network (such as an internal company Web server) instead of connecting to the proxy server.

The Programs tab of the Internet Options dialog box, shown in Figure 16-21, allows you to configure the programs that are associated with particular services. For example, if a user is browsing a Web site and selects an e-mail address link, Internet Explorer must launch the appropriate e-mail program. Other configurable services include the HTML editor, the newsgroup client, the program to be used to establish a call across the Internet, and the programs to access the user s calendar and contact list.
