Notifies the subscriber if the Microsoft Distributed Transaction Coordinator (DTC) transaction starts, commits, or aborts. The subscriber is also notified when the resource manager retrieves prepare information from the transaction manager. The events are published to the subscriber using the COM+ Events service, a loosely coupled events system that stores event information from different publishers in an event store in the COM+ catalog.
