6.1.1 Protocols List

The File Services protocols include two sets of protocols: the core protocols that provide the file services functionality and a set of protocols that are required for an implementation of the core protocols (as listed in the Normative References section of the core protocols technical specifications) or provide core networking functionality. The latter set of protocols is referred to as the Networking Protocols Group as described in the "Overview" section of this document.

The following table lists the core protocols included in File Services. This list does not include data structures, file structures, or algorithms that these core protocols depend on. The details for these technical dependencies are documented in the technical specifications for each core protocol.

Protocol Name


Document Short Name

Common Internet File System (CIFS) Browser Protocol

Enables interaction with the browser service that creates and maintains a view of resources that are available on a network.


Disk Management Remote Protocol

Enables remote management of disks on a computer running Windows Server 2003 operating system, Windows XP operating system, or Windows 2000 operating system.


Distributed Component Object Model (DCOM) Remote Protocol

Enables a client object to call the methods of a remote COM object over a network. DCOM also monitors connection integrity between server objects and clients.


Encrypting File System Remote (EFSRPC) Protocol

Enables performing maintenance and management operations on encrypted data that is stored remotely and accessed over a network.


Server Message Block (SMB) Protocol

Requests file and print services from server systems over a network.


Server Message Block (SMB) Version 2 Protocol

Update of SMB 1.0 for Windows Vista operating system, Windows Server 2008 operating system, Windows 7 operating system, and Windows Server 2008 R2 operating system.


Server Service Remote Protocol

Provides the capability to manage file and print serving resources, and responds to requests made by other computers for shared resources on the local computer.


Content Indexing Services Protocol

Provides methods of querying and managing index catalogs using a named pipe.


Distributed File System (DFS): Namespace Management Protocol.

Maps clients logical file requests to server physical files.


Removable Storage Manager (RSM) Remote Protocol

Enables remote management of removable media libraries on Windows 2000 and Windows XP.


Virtual Disk Service (VDS) Remote Protocol

Enables remote management of disks on a computer running Windows Server 2008.


Web Distributed Authoring and Versioning (WebDAV) Protocol: Client Extensions

Provides file access and content management over the Internet, enabling an Internet-based file system.


The following sections provide general functionality followed by a specific overview of each protocol and a description of the logical dependencies among the protocols that provide services in those areas.
