The DTC Proxy calls on this method if the connection to the transaction manager goes down and the resource manager's transaction object is prepared (that is, after the resource manager has called the ITransactionEnlistmentAsync::PrepareRequestDone method). In general, the proxy calls the ITransactionResourceAsync::TMDown method to inform the resource manager that it must perform recovery on that particular transaction.

If the connection between the DTC Proxy and the transaction manager fails, the DTC Proxy first calls the resource manager's ITransactionResourceAsync::TMDown method once for each transaction in which the resource manager is enlisted. The DTC Proxy then calls the resource manager's IResourceManagerSink::TMDown method. This ensures that the resource manager is informed of the failure even if it has no enlisted transactions.
