SYMPTOMS
Consider the following scenario. You install Microsoft Windows Server 2003 from an installation CD that includes Microsoft Windows Server 2003 Service Pack 1 (SP1). You do not install Microsoft Internet Information Services (IIS) 6. After you finish installing Windows Server 2003 SP1, you use the Add or Remove Programs item in Control Panel to install IIS 6. When you are prompted to insert a Windows Server 2003 CD to complete the installation of IIS, you insert a Windows Server 2003 CD that does not include SP1.
In this scenario, you may receive an error message that resembles the following when you try to view a Web site that is hosted on IIS 6:
Service Unavailable
