Distributed Transaction Coordinator is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Distributed Transaction Coordinator service is started, it is running as NT AUTHORITY\NetworkService in its own process of msdtc.exe. If Distributed Transaction Coordinator fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the MSDTC service is not running because of the error.
Distributed Transaction Coordinator is unable to start, if at least one of the following services is stopped or disabled:
