A NetBIOS node type that uses a mix of b-node and p-node communications to register and resolve NetBIOS names . M-node first uses broadcast resolution; then, if necessary, it uses a server query. See also network basic input/output system (NetBIOS).
- master installation
A customized installation of Windows that you duplicate onto one or more destination computers.
- master properties
In Internet Information Services (IIS), properties that are set at the computer level that become default settings for all Web or File Transfer Protocol (FTP) sites on that computer.
- member server
A server that is joined to a domain but is not a domain controller. Member servers typically function as file servers, application servers, database servers, Web servers, certificate servers, firewalls, or remote access servers. See also domain; domain controller.
- Message Queuing
A message queuing and routing system for Windows that enables distributed applications running at different times to communicate across heterogeneous networks and with computers that may be offline. Message Queuing provides guaranteed message delivery, efficient routing, security, and priority- based messaging. Formerly known as MSMQ .
A hierarchical store of configuration information and schema that is used to configure Internet Information Services (IIS). The metabase performs some of the same functions as the system registry, but it uses less disk space. In physical terms, the metabase is a combination of the MetaBase.xml and MBSchema.xml files and the in-memory metabase.
- metabase configuration file
A file that stores Internet Information Services (IIS) configuration settings to disk. This file is named MetaBase.xml by default. When IIS is started or restarted, the configuration settings are read from MetaBase.xml into the IIS cache in memory, which is called the in-memory metabase.
- metabase schema
The master configuration file (MBSchema.xml) supplied with Internet Information Services (IIS) that contains all of the predefined properties from which metabase entries are derived.
Data about data. For example, the title, subject, author, and size of a file constitute the file s metadata.
- Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2)
An encrypted authentication mechanism for PPP connections that provides stronger security than CHAP and MS-CHAP v1. MS-CHAP v2 provides mutual authentication and asymmetric encryption keys. See also Point-to-Point Protocol (PPP).
- Microsoft Management Console (MMC)
A framework for hosting administrative tools called snap-ins . A console might contain tools, folders or other containers, World Wide Web pages, and other administrative items. These items are displayed in the left pane of the console, called a console tree . A console has one or more windows that can provide views of the console tree. The main MMC window provides commands and tools for authoring consoles. The authoring features of MMC and the console tree itself might be hidden when a console is in User Mode. See also console tree; details pane; snap-in.
- Microsoft Point-to-Point Encryption (MPPE)
A 128-bit key or 40-bit key encryption algorithm using RSA RC4. MPPE provides for packet confidentiality between the remote access client and the remote access or tunnel server, and it is useful where Internet Protocol security (IPSec) is not available. MPPE 40-bit keys are used to satisfy current North American export restrictions. MPPE is compatible with Network Address Translation. See also remote access server.
In file management, to move files or programs from an older file format or protocol to a more current format or protocol. For example, WINS database entries can be migrated from static WINS database entries to dynamically registered DHCP entries.
In Active Directory, to move Active Directory accounts, resources, and their associated security objects from one domain to another.
In Windows NT, to change the domain controller operating system from Windows NT to an operating system with Active Directory, such as Windows 2000 or Windows Server 2003. A migration from Windows NT can include in-place domain upgrades, domain restructuring, or both.
In Remote Storage, to copy an object from local storage to remote storage.
See also Active Directory; Dynamic Host Configuration Protocol (DHCP); Windows Internet Name Service (WINS).
See definition for migrate.
- Mini-Setup wizard
A wizard that starts the first time a computer boots from a hard disk that has been duplicated. The wizard gathers any information that is needed for the newly duplicated hard disk.
- mirror set
A fault-tolerant partition created with Windows NT 4.0 or earlier that duplicates data on two physical disks. Windows XP and the Windows Server 2003 family do not support mirror sets. In the Windows Server 2003 family, you must create mirrored volumes on dynamic disks. See also dynamic disk; mirrored volume.
- mirrored volume
A fault-tolerant volume that duplicates data on two physical disks. A mirrored volume provides data redundancy by using two identical volumes, which are called mirrors , to duplicate the information contained on the volume. A mirror is always located on a different disk. If one of the physical disks fails, the data on the failed disk becomes unavailable, but the system continues to operate in the mirror on the remaining disk. You can create mirrored volumes only on dynamic disks on computers running the Windows 2000 Server or Windows Server 2003 families of operating systems. You cannot extend mirrored volumes. See also dynamic disk; dynamic volume; fault tolerance; RAID-5 volume.
- mounted drive
A drive attached to an empty folder on an NTFS volume. Mounted drives function the same as any other drive, but are assigned a label or name instead of a drive letter. The mounted drive s name is resolved to a full file system path instead of just a drive letter. Members of the Administrators group can use Disk Management to create mounted drives or reassign drive letters . See also NTFS file system.
- Multicast Address Dynamic Client Allocation Protocol (MADCAP)
An extension to the DHCP protocol standard used to support dynamic assignment and configuration of IP multicast addresses on TCP/IP-based networks. See also Dynamic Host Configuration Protocol (DHCP); multicasting; Transmission Control Protocol/Internet Protocol (TCP/IP).
- multicast scope
A range of multicast group IP addresses in the Class D address range that are available to be leased or assigned to multicast DHCP clients by DHCP. See also Dynamic Host Configuration Protocol (DHCP); IP address; lease; multicasting.
The process of sending a message simultaneously to more than one destination on a network.
- multihomed computer
A computer that has multiple network adapters or that has been configured with multiple IP addresses for a single network adapter. See also IP address; network adapter.
