Recommended Hotfixes for Windows Server 2012 Failover Clusters

  • Articolo

Today, Microsoft released Knowledge Base article 2784261, which describes the hotfixes we recommend being installed on all Windows Server 2012 failover clusters.  This includes Exchange database availability groups that are running on Windows Server 2012, as well.

Although these hotfixes are generally recommended for all customers, we recommend that you evaluate each fix to determine whether it applies to your environment. If you determine a server in your organization is affected by the problem(s) that a fix addresses, install the fix on each cluster node by using the procedures that are described in Knowledge Base article 174799: Patching Windows Server Failover Clusters.

The recommended hotfixes include two important updates:

  • 2848344 – This is an updated roll-up hotfix that replaces 2838669.  This fix is most important for any Hyper-V deployment, and critical for any deployment using DPM for backup.
  • 2838043 – This is a fix for NetName, that addresses a password synchronization issue.  This has been a top CSS call generator, where Repair was used in the past.

The hotfixes we recommend for Windows Server 2012 failover clusters are as follows:
