COM+ System Application logs on as LocalSystem and runs in its own process of dllhost.exe. It does not share its process with other services. If COM+ System Application fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the COMSysApp service has failed to start.
COM+ System Application won't start, if the following system components are stopped or disabled:
