This object creates an instance of the DFS Client Computer class for each discovered computer, and is used to enable client computers to monitor the availability of DFS Namespaces.
This object is disabled by default. When enabled, this object runs the DFSClientDiscovery.vbs script.
Enable this object to test a computer’s ability to access DFS namespaces, folders (links), and folder targets. Do not enable this object on a large number of computers because the namespace testing can create a large amount of network traffic. Instead, use overrides to enable this object only on specific computers.
