2.2 Protocol Summary

File Server Resource Manager Protocol

This protocol describes operating system, file system, and storage concepts. The protocol exposes a set of interfaces that enable tools in a client role to manage the following:

Directory quotas to limit the amount of storage capacity in a directory.

File screens to limit the type of files in a directory.

Setup of the file classification that defines the classification property schema and rules to automatically classify files.

File management tasks that apply simple commands to filtered groups of files.

Storage reports that cover storage usage and trend analysis.

Query and modification of file classification values by retrieving and setting classification properties for files, as provided by the FSRM component server role.

Workstation Service Remote Protocol

This protocol is used to configure the properties and behavior of a Server Message Block (SMB) Network Redirector (SMB Network Redirector) on a computer. It is also used to configure domain membership. For example, this protocol can be used to query the platform identifier, computer name, or major and minor version numbers of the operating system that runs on a remote computer. The File Services Management system uses this protocol to configure an SMB Network Redirector. Other capabilities of this protocol are not used by the File Services Management system.

[MS-WKST]

Server Service Remote Protocol

This protocol is used to enable file and printer sharing and named pipe access to the server through the Server Message Block (SMB) Protocol [MS-SMB]. The protocol is also used for remote administration of servers that are running Windows operating systems.

[MS-SRVS]

Remote Administration Protocol

This protocol is used for legacy administrative functions which include tasks, such as share maintenance and printer maintenance on LAN Manager servers. In addition, the Common Internet File System (CIFS) Browser Protocol uses the Remote Administration Protocol to enumerate the servers on the network. Most of this protocol's functionality has been superseded by the Workstation Service Remote Protocol [MS-WKST], and the Server Service Remote Protocol [MS-SRVS].

Distributed File System (DFS): Namespace Management Protocol

This protocol is used to create and administer Distributed File System (DFS) namespaces. DFS namespaces enable the creation of a virtual, contiguous file system namespace to unify multiple namespaces.

[MS-DFSNM]

DFS Replication Helper Protocol

This protocol is a DCOM protocol that can be divided into two parts. One part consists of interfaces to change, modify, and delete configuration objects in Active Directory. The second part is an interface to monitor Distributed File System-Replication (DFS-R) on a server [MS-FRS2] and to collect various statistics about the DFS Replication operation.

[MS-DFSRH]

Distributed File System Replication Protocol

This protocol is used to replicate files between file servers. It is a multimaster replication, which enables files to be changed by any member that participates in replicating shared files. Because it uses an optimistic replication strategy, files can be updated without any prior consensus or serialization. DFS-R uses the Remote Differential Compression (RDC) algorithm. DFS-R supersedes the older FRS replication protocol.

[MS-FRS2]

File Replication Service Protocol

This protocol is an RPC protocol that is used on file servers to replicate files and folders among file servers on the network. This protocol enables multimaster file and folder replicas to be synchronized on multiple file servers. FRS is used to maintain duplicate copies of data files in system volume (SYSVOL) system folders on domain controllers in a domain. FRS can also be used to replicate data files among DFS shares.

[MS-FRS1]

Remote Differential Compression (RDC) Algorithm

This algorithm enables efficient synchronization of files with a remote source by using compression techniques to minimize the amount of data that is sent between a source location and a target location. This algorithm is used by the Distributed File System: Replication (DFS-R) Protocol.
