What is DFS?
The Distributed File System (DFS) functions provide the ability to logically group shares on multiple servers and to transparently link shares into a single hierarchical namespace. DFS organizes shared resources on a network in a treelike structure.
DFS supports stand-alone DFS namespaces, those with one host server, and domain-based namespaces that have multiple host servers and high availability. The DFS topology data for domain-based namespaces is stored in Active Directory. The data includes the DFS root, DFS links, and DFS targets.
