Error message when you try to view a Web site that is hosted on IIS 6: "Service unavailable"

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
Additionally, one of the following messages may be written to the Application log:
Warning message
Event Type: Warning
Event Source: W3SVC
Event ID: 1009
Description: A process serving application pool AppPool terminated unexpectedly. The process id was ProcessID. The process exit code was '0xffffffff'.
Error message
Event Type: Error
Event Source: DCOM
Event ID: 10016
Description: The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID ClsID to the user NT AUTHORITY\NETWORK SERVICE SID SID.
This security permission can be modified using the Component Services administrative tool.
Note AppPool represents an application pool in IIS 6, ProcessID represents the ID for a process, ClsID represents the identification for a COM object, and SID represents the security identifier for a process.

CAUSE

This issue occurs if you do not reinstall Windows Server 2003 SP1 after you install IIS 6.

RESOLUTION

To resolve this issue, reinstall Windows Server 2003 SP1 after you install IIS 6.
