SYMPTOMS

Consider the following scenario:
  • You create a failover cluster on some computers that are running Windows Server 2008.
  • An IP version 6 (IPv6) IP address fails over from one cluster node to another cluster node.
In this scenario, the Cluster service takes about 30 seconds to fail over the IPv6 IP address. This causes clients to wait for about 30 seconds to reconnect to the IPv6 IP address.

CAUSE

This issue occurs because the Cluster Resource DLL (ClusRes.dll) module only sends gratuitous Neighbor Advertisement messages for IP version 4 (IPv4) IP addresses, and not for IPv6 IP addresses.

RESOLUTION

To resolve this issue, install the following hotfix on the affected cluster nodes that are running Windows Server 2008. After you install the following hotfix, the failover time for IPv6 IP addresses is reduced to several seconds.
