Default Behavior

Distributed Transaction Coordinator is a Win32 service. In Windows XP it won't start until the current user starts it. When the Distributed Transaction Coordinator service is started, it is running as NT AUTHORITY\NetworkService in its own process of msdtc.exe. If the Distributed Transaction Coordinator fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the MSDTC service has failed to start.

Dependencies

Distributed Transaction Coordinator depends on the following system components:
