"XACT_E_CONNECTION_DOWN" error on SQL Server instances after you restart MS DTC in Windows 8 or Windows server 2012

View products that this article applies to.

Symptoms

This issue occurs on a Windows 8-based or Windows Server 2012-based SQL Server cluster. When you restart Microsoft Distributed Transaction Coordinator (MS DTC), SQL Server instances might not be able to reconnect to MS DTC successfully. Therefore, distributed transactions might fail with the error message until you restart the SQL server instances.

Note When this issue occurs, SQL Server does not log any message of losing connection.

Cause

This issue occurs because the MS DTC proxy does not notify SQL Server that the connection is lost after MS DTC restarts. Therefore, SQL Server does not release a pointer and does not reinitialize the MSDTC proxy until it restarts.
