This rule monitors whether DFS failed to create a new namespace because the root directory for the namespace overlaps another namespace’s root directory. It does this by looking for the presence of DfsSvc event 14505 in the System log in Event Viewer.
This can occur if while creating a namespace, the administrator changes the local path of the shared folder storing the namespace root to a location that is a subdirectory of a folder already hosting another namespace.
To resolve this issue, use the DFS Management snap-in to recreate the namespace. To do so, see Create a DFS Namespace (http://go.microsoft.com/fwlink/?LinkId=186533).
Note: To create a domain-based namespace, you must be a member of the Domain Admins group in the domain that you want to create the namespace, or have been delegated permissions. To create a stand-alone namespace, you must be a member of the Local Administrators group on the namespace server.
