The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the heuristics attribute has been configured to enable the Defense Message System. By default, the heuristics attribute is not configured. If the Exchange Server Analyzer finds that the heuristics attribute is set to 256, the Exchange Server Analyzer displays a non-default configuration message.

The Exchange Server Analyzer reports this configuration for informational purposes only. No action is required.

The Defense Message System (DMS) Program was established by the Under Secretary of Defense (Acquisition) to facilitate and coordinate development of an integrated common-user message system that satisfies writer-to-reader requirements, reduces cost and staffing levels, and improves functionality, security, survivability, and availability.

For more information about the Defense Message System, see the Lockheed Martin Web site (http://www.lockheedmartin.com).
