2.3.2 Dependencies on Other Systems/Components
The File Management Services system depends on the following external systems and components:
Object store: Used to store files and metadata.
Active Directory system: Used to store Distributed File System (DFS) namespace metadata. If an Active Directory system is unavailable, an administrator cannot create a domain-based Distributed File System (DFS) namespace and cannot use the Distributed File System Replication (DFS-R) Services.
Authentication Services system: Used to authenticate admin clients and the admin server. The Authentication services are described in the Authentication Services Protocols Overview [MS-AUTHSOD].
