Using VSE/ENSTP in a Microsoft Cluster environment

VSE and ENSTP supports a shared disk model and as such, does not interfere with the failover process on a Microsoft Cluster. But, the On Access Scanning service is not a cluster service and not installed as a failover group resource.

Functionality Explained
 VSE and ENSTP install s on each system (or node) in the cluster, and scans as it would on any other server. If a node fails, the surviving nodes with VSE or ENSTP installed continue to operate as usual. The same is true when the node that failed comes back online - the VSE or ENSTP that is 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 so as not to impact failover operations. If you have a failover issue believed to be caused by McAfee products, please contact Technical Support.
