Using ENS Threat Prevention and VSE in a Microsoft Cluster environment

ENS Threat Prevention and VSE support a shared disk model and as such, do not interfere with the failover process on a Microsoft Cluster. But, the On Access Scanning service is not a cluster service and is not installed as a failover group resource.

Functionality Explained
 ENS Threat Prevention and VSE install on each system or node in the cluster, and scan as they would on any other server. If a node fails, the surviving nodes with ENS Threat Prevention and VSE installed continue to operate as usual. The same is true when the node that failed comes back online - ENS Threat Prevention and VSE installed on it will operate normally.

Microsoft Knowledge Base article 250355 http://support.microsoft.com/kb/250355 deals with potential issues with anti-virus software and failover operations on clusters. It also provides troubleshooting tips for these types of issues.

IMPORTANT: McAfee designs its products to not impact failover operations. If you have a failover issue that you think is caused by McAfee products, contact Technical Support.
