Remarks
An MSDTC proxy can only service one ITransactionImportWhereabouts::GetWhereabouts or ITransactionImportWhereabouts::GetWhereaboutsSize call at a time. If multiple clients call these methods concurrently, the calls might fail with XACT_E_ALREADYINPROGRESS. To avoid this, clients should cache the location and size for each transaction manager, or provide their own synchronization to calls to these methods for each transaction manager.
