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.
