For example, the Direct Mailer Service (DMLService.exe) may fail under the following circumstances:
- You run Direct Mailer Service on a multiprocessor system.
-and-
- You try to use a Microsoft Commerce Server 2000 pipeline to create an instance of a Visual Basic COM+ component.
In this scenario, the following event is logged in the application event log:
Pipeline Error: Component Execution failed for component[0x7] hr: 0x80004005
ProgID: DMPersonalization.SentStatus
Loading Component DMPersonalization.SentStatus failed because Global Interface Table is unable to provide a valid marshaled interface pointer for the component Automation error Unspecified error
