When you use Microsoft Message Queue Server (MSMQ) on your computer running Windows NT 4.0, MSMQ can be configured to guarantee "only once" delivery of transactional messages without duplicate messages for forty-five days. However, it is possible, under certain conditions, to receive duplicate transactional messages within a twenty-four hour time frame.
