SYMPTOMS

An access violation occurs in Microsoft Distributed Transaction Coordinator (MS DTC) when a client that is connected to an MS DTC clustered resource tries to create an enlistment in MS DTC. For example, this problem may occur if a computer where Microsoft SQL Server is installed loses synchronization with an MS DTC server and then tries to enlist a transaction in MS DTC.

CAUSE

This problem occurs because of two race conditions in the MS DTC code. In one race condition, the transaction manager (TM) tries to create a trace before an interface pointer to perform that trace exists. A second race condition exists when the MS DTC proxy sends TMDown notifications to enlistments and resource managers.
