The following terms are defined in [MS-GLOS]:
Active Directory (AD)
backup browser server
domain master browser server
master browser server
primary domain controller (PDC)
The following terms are specific to this document:
Backup Domain Controller (BDC): A backup domain controller (BDC) maintains a copy of the directory database. This copy is synchronized periodically and automatically with the primary domain controller (PDC). BDCs also authenticate user logons and can be promoted to function as the PDC. Multiple BDCs can exist in a domain.
frame: A CIFS Browser Protocol message.
group name: A 16-byte, formatted NetBIOS computer name, which can have multiple IP addresses assigned to it; that is, multiple NetBIOS nodes (processor locations) can use this name to register for services, as specified in [RFC1001].
machine group: A generic reference to a domain or a workgroup, of which a specified machine is a member. A computer implementing the CIFS Browser Protocol must be a member of either a workgroup or a domain.
nonbrowser server: A server that wants to be enumerated to clients of the CIFS Browser Protocol that does not otherwise implement elements of the CIFS Browser Protocol.
preferred master browser server: A machine that functions as a typical backup browser server except that it forces a browser election when it is started. Preferred master browser servers are given an advantage in elections. By configuring one or more machines as preferred master browser servers, a network administrator can actually choose particular machines for this role.
subnet: A logical division of a network. Subnets provide a multilevel hierarchical routing structure for the Internet. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. Subnets are useful for both security and performance reasons. In general, broadcast messages are scoped to within a single subnet. For more information about subnets, see [RFC1812].
unique name: A 16-byte, formatted NetBIOS computer name that can have only one IP address assigned to it; that is, only a single NetBIOS node (or processing location) can use this name to register for services, as specified in [RFC1001].
Windows Internet Name Service (WINS): A name service for the NetBIOS protocol that is specifically designed to ease transition to a TCP/IP–based network.
MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as described in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
