Enterprise Services applications typically offer critical middle-tier functionality. If your Enterprise Services applications reside on the same computer as the processes that call these applications, you can add an additional layer of security—beyond the security that role-based access controls offer—by disabling COM+ Network Access. Disabling COM+ Network Access prevents network access to all Enterprise Services applications.
