DFS Namespace
A virtual view of shared folders on servers provided by DFS. A DFS namespace consists of a root and many links and targets. The namespace starts with a root that maps to one or more root targets. Below the root are links that map to their own targets.
Domain-based DFS namespace
A DFS namespace whose configuration information is stored in Active Directory.
DFS Link (folder with targets)
A component in a DFS path that lies below the root and maps to one or more link targets.
DFS Link Target (folder target)
The mapping destination of a link. A link target can be any UNC path, such as a shared folder or another DFS path.
