SYMPTOMS
When an application calls the CoRegisterClassObject function, Microsoft Windows Installer tries to repair the application. This problem occurs when the application does not have to be repaired.

Consider the following scenario:
 * On a computer that is running Microsoft Windows Server 2003 or Microsoft Windows XP with Service Pack 2 (SP2), Microsoft Windows Installer installs an application.
 * The application is a resilient application.
 * The application calls the CoRegisterClassObject function.

In this scenario, Windows Installer tries to repair the application.



CAUSE
When the application calls the CoRegisterClassObject function, the call impersonates the Network Service account. When Windows Installer components have not been assigned the Read permission to the Network Service account, resiliency causes Windows Installer to try to repair the application.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Windows Server 2003 Service Pack 2.



MORE INFORMATION
In Windows Server 2003 and in Windows XP SP2, the Remote Procedure Call service runs under the Network Service account. In versions of Microsoft Windows earlier than Windows Server 2003 and Windows XP SP2, the Remote Procedure Call service runs under the SYSTEM account.

In Windows Server 2003 and in Windows XP SP2, calls to Windows Installer do not impersonate the SYSTEM account. Instead, calls to Windows Installer impersonate the Network Service account.
