Microsoft Distributed Transaction Coordinator

The Distributed Transaction Coordinator, short DTC is a system service on Microsoft Windows NT -based operating systems, which is used for coordination of atomic operations in the use of distributed application scenarios.

A distributed transaction extends over at least two resources, such as databases, message queues, and file systems. If the system service is stopped, dependent services can not be performed and no transactions are executed across system boundaries more. This includes for example the transaction- call procedures on other systems ( Remote Procedure Call) or the use of the introduced with Windows Vista Service Kernel Transaction Manager (KTM ) and the Transactional NTFS ( TxN ).
