This article describes the hotfixes and updates that we recommend that you install on each node of a Windows Server 2008-based failover cluster. When you update your Windows Server 2008-based failover cluster, you help reduce downtime. You also help decrease the number of support issues that you experience.

Note We recommend that you evaluate these hotfixes and updates to determine whether they might resolve problems in your environment. If you determine that cluster nodes in your environment may be affected by the problems that an update or hotfix addresses, install the hotfix or update on each one of the cluster nodes in your environment.

Use the information in the "More information" section to help you determine whether a particular hotfix or update applies to your server cluster. Before you install a particular hotfix or update, we recommend that you review the original Microsoft Knowledge Base (KB) article that describes that hotfix or update.
