COM+ System Application is a Win32 service. In Windows XP it won't start until the current user starts it. When the COM+ System Application service is started, it is running as LocalSystem in its own process of dllhost.exe. If the COM+ System Application fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the COMSysApp service has failed to start.
COM+ System Application depends on the Remote Procedure Call (RPC) service.
