This article describes a conflict between Microsoft SQL Server and Microsoft Distributed Transaction Coordinator service (MSDTC) in Windows Server 2012 R2. A hotfix is available to fix this issue. The hotfix has a prerequisite.

Symptoms

Consider the following scenario:

  • You're using SQL Server in combination with MSDTC.

  • You creates a distributed transaction that spans two or more database instances.

  • During two-phase commit, SQL Server prepares the transaction, but its database has to restart.

  • As part of the database restart, SQL Server will try to recover its log, and will have to communicate with MSDTC for outcome by calling Reenlist.

In this scenario, when SQL Server calls Reenlist during the database recovery, the MSDTC proxy throws an error message XACT_E_RECOVERYALREADYDONE (0x8004D104L) that indicates Reenlist is no longer available to be called.

Resolution

To fix this issue, we have released a hotfix. Even though this issue is observed only in Windows Server 2012 R2, the hotfix also applies to Windows 8.1 and Windows RT 8.1. Important If you install a language pack after you install this hotfix, you must reinstall this hotfix. Therefore, we recommend that you install any language packs that you need before you install this hotfix. For more information, see Add language packs to Windows.
