The MS DTC issue that is fixed in Windows Server 2008 R2 MS DTC Hotfix Rollup Package 1

This article describes the Microsoft Distributed Transaction Coordinator (MS DTC) issue that is fixed in Windows Server 2008 R2 MS DTC Hotfix Rollup Package 1.

Issue that is fixed in this hotfix rollup package

This hotfix rollup package fixes the following issue that was not previously documented in a Microsoft Knowledge Base article.

Consider the following scenario:

• You have a failover cluster that is running Windows Server 2008 R2.
• You add a MS DTC resource to the cluster. Additionally, you configure the MS DTC resource to depend on a third-party disk resource.
• You try to bring the MS DTC resource online.

In this scenario, you cannot bring the MS DTC resource online. Additionally, an error message that resembles the following is logged in the Application log:

Log Name: System
Source: Microsoft-Windows-FailoverClustering
Date: <Date Time>
Event ID: 1146
Task Category: Resource Control Manager
Description: The cluster resource host subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually due to a problem in a resource DLL. Please determine which resource DLL is causing the issue and report the problem to the resource vendor.

This problem occurs because the MS DTC resource cannot identify a dependent disk when a third-party disk resource is used.
