This document uses the following terms:
Active Directory: The Windows implementation of a general-purpose directory service, which uses LDAP as its primary access protocol. Active Directory stores information about a variety of objects in the network such as user accounts, computer accounts, groups, and all related credential information used by Kerberos [MS-KILE]. Active Directory is either deployed as Active Directory Domain Services (AD DS) or Active Directory Lightweight Directory Services (AD LDS), which are both described in [MS-ADOD]: Active Directory Protocols Overview.
Active Directory Domain Services (AD DS): A directory service (DS) implemented by a domain controller (DC). The DS provides a data store for objects that is distributed across multiple DCs. The DCs interoperate as peers to ensure that a local change to an object replicates correctly across DCs. AD DS is a deployment of Active Directory [MS-ADTS].
client machine GUID: Each client machine is assigned a unique GUID by the machine manufacturer and is stored in the SMBIOS of the client machine as per [DMTF-DSP0134].
deployment agent unattend: Unattended instructions that provide input for all or some steps performed by the deployment agent. If unattended instructions do not provide input for certain steps, the deployment agent asks the user for input.
domain: A set of users and computers sharing a common namespace and management infrastructure. At least one computer member of the set must act as a domain controller (DC) and host a member list that identifies all members of the domain, as well as optionally hosting the Active Directory service. The domain controller provides authentication of members, creating a unit of trust for its members. Each domain has an identifier that is shared among its members. For more information, see [MS-AUTHSOD] section 188.8.131.52 and [MS-ADTS].
driver package: A collection of the files needed to successfully load a driver. This includes the device information (.inf) file, the catalog file, and all of the binaries that are copied by the .inf file. Multiple drivers packaged together for deployment purposes.
globally unique identifier (GUID): A term used interchangeably with universally unique identifier (UUID) in Microsoft protocol technical documents (TDs). Interchanging the usage of these terms does not imply or require a specific algorithm or mechanism to generate the value. Specifically, the use of this term does not imply or require that the algorithms described in [RFC4122] or [C706] must be used for generating the GUID. See also universally unique identifier (UUID).
multicast namespace: Hosts multiple content that are available to clients using multicast sessions. Identification by a unique name is required. All content under a multicast namespace is available for transmission over multicast transmission.
OS deployment process: Set of operations that must be performed by the deployment agent to prepare and deploy an OS image on client machine. It also includes steps that are performed by a deployed OS to bring the OS to a functioning state. Each step in the process might require input from the user.
OS image: Set of files required to deploy/install an Operating System on a machine. Each OS image is in either Virtual Hard Drive (VHD) or Windows Imaging (WIM) format. Each OS image also has associated OS image metadata.
OS Image Unattend: Unattended instructions that provide input for some or all steps performed by the Deployed OS to bring OS to a functioning state. If Unattended instructions do not provide input for certain steps, Deployed OS asks user for input.
Unicode string: A Unicode 8-bit string is an ordered sequence of 8-bit units, a Unicode 16-bit string is an ordered sequence of 16-bit code units, and a Unicode 32-bit string is an ordered sequence of 32-bit code units. In some cases, it could be acceptable not to terminate with a terminating null character. Unless otherwise specified, all Unicode strings follow the UTF-16LE encoding scheme with no Byte Order Mark (BOM).
WDS server: A Windows Deployment Services (WDS) server that communicates with clients by using the WDS OS Deployment Protocol to aid in deployment of an OS image on a client machine. Clients also communicate to a WDS server to request initiation/setup of multicast sessions for content available in multicast namespace on server.A WDS server provides an extensible mechanism to allow service providers to provide services to clients.
MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
