Cluster service sends unnecessary registry key change notifications among cluster nodes in Windows Server 2008 or in Windows Server 2008 R2

Symptoms

Consider the following scenario:

  • You create a failover cluster among many nodes that are running Windows Server 2008 or Windows Server 2008 R2 with the Failover Cluster feature installed.

  • A cluster-aware application, such as a SQL Server 2012 AlwaysOn Availability Group, registers for multiple registry key change notifications when changes are made to the cluster.

  • There are some registry changes in the cluster. This is the expected behavior in a cluster that works correctly.

In this scenario, the Cluster service sends unnecessary notifications among cluster nodes. Specifically, each registry key change notification is sent to every cluster node by every other cluster node. The unnecessary propagation of registry notifications limits network bandwidth and is a serious issue in a large cluster environment.

Windows Server 2008 file information notes

Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    Version

  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
