This rule monitors for duplicate DFS folders (links). It does so by looking for the presence of DfsSvc event 14547 in the System log of Event Viewer.
If a script attempts to create the same DFS folder in a domain-based namespace (Windows Server 2008 mode) at approximately the same time on different namespace servers, the DFS Namespace service could create two identically named folders.
To remove duplicate folders, you must be a member of the Domain Admins group in the domain in which the namespace exists. To remove duplicate folders, see the DFS Namespaces FAQ (http://go.microsoft.com/fwlink/?LinkId=171023).
