4. In the Windows Components Wizard, under the Components list, click Internet Information Services.
5. In the Windows Components Wizard, click Next. The Windows Components Wizard displays the Configuring Components screen with a status bar that displays the progress of the configuration. If you are prompted, insert the Windows XP CD-ROM into the CD-ROM drive.
