Symptoms

Issue 1

Consider the following scenario:

  • You install the failover cluster feature and the Services for NFS feature on a computer that is running Windows Server 2008 R2.

  • You configure a Network File System (NFS) share to allow only Kerberos v5 authentication (Krb5) or Kerberos v5 integrity checking and authentication (Krb5i).

  • You export the NFS share to a cluster node.

  • The NFS share fails over to another cluster node.

In this scenario, you can no longer access the NFS share unless you disconnect all connections to the server and then reconnect to the server.

Issue 2

Assume that you configure a Windows Server 2008 R2-based Network File System (NFS) share to allow only Kerberos v5 authentication (Krb5) or Kerberos v5 integrity checking and authentication (Krb5i). In this scenario, some NFS client implementations cannot mount the NFS share from a failover cluster or from a stand-alone server when the AUTH_SYS authentication is disabled.

Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" 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.
