L2TP

See definition for Layer Two Tunneling Protocol (L2TP).

LAN

See definition for local area network (LAN).

Language for non-Unicode programs

A Regional and Language Options setting that specifies the default code pages and associated bitmap font files for a specific computer that affects all of that computer's users. The default code pages and fonts enable a non-Unicode application written for one operating system language version to run correctly on another operating system language version. Formerly known as system locale.

Last Known Good Configuration

A hardware configuration available by pressing F8 during startup. If the current hardware settings prevent the computer from starting, the last known good configuration can allow you to start the computer and examine the configuration. When the last known good configuration is used, later configuration changes are lost.

Layer 2 forwarding (L2F)

Permits the tunneling of the link layer of higher-level protocols. Using these tunnels, it is possible to separate the location of the initial dial-up server from the physical location at which the dial-up protocol connection is terminated and access to the network is provided. See also tunnel.

Layer Two Tunneling Protocol (L2TP)

An industry-standard Internet tunneling protocol that provides encapsulation for sending Point-to-Point Protocol (PPP) frames across packet-oriented media. For IP networks, L2TP traffic is sent as User Datagram Protocol (UDP) messages. In Microsoft operating systems, L2TP is used in conjunction with Internet Protocol security (IPSec) as a virtual private network (VPN) technology to provide remote access or router-to-router VPN connections. L2TP is described in RFC 2661. See also Internet Protocol security (IPSec); Point-to-Point Protocol (PPP); tunnel.

library

A data-storage system, usually managed by Removable Storage. A library consists of removable media (such as tapes or discs) and a hardware device that can read from or write to the media. There are two major types of libraries: robotic libraries (automated multiple-media, multidrive devices) and stand-alone drive libraries (manually operated, single-drive devices). A robotic library is also called a jukebox or changer. See also Removable Storage.

library request

A request for an online library or stand-alone drive to perform a task. This request can be issued by an application or by Removable Storage.

Lightweight Directory Access Protocol (LDAP)

The primary access protocol for Active Directory. LDAP version 3 is defined by a set of Proposed Standard documents in Internet Engineering Task Force (IETF) RFC 2251. See also Active Directory; protocol.

Line Printer

A connectivity tool that runs on client systems and is used to print files to a computer running an LPD server.

Line Printer Daemon (LPD)

A service on the print server that receives documents (print jobs) from Line Printer Remote (LPR) tools running on client systems. See also Line Printer Remote (LPR); print job; print server.

Line Printer Port Monitor

A port monitor that is used to send jobs over TCP/IP from the client running Lprmon.dll to a print server running a Line Printer Daemon (LPD) service. Line Printer Port Monitor can be used to enable Internet printing, UNIX print servers, or Windows 2000 print servers over a TCP/IP network. See also Line Printer Daemon (LPD); Transmission Control Protocol/Internet Protocol (TCP/IP).

Line Printer Remote (LPR)

A connectivity tool that runs on client systems and is used to print files to a computer running an LPD server. See also Line Printer Daemon (LPD).

local area network (LAN)

A communications network connecting a group of computers, printers, and other devices located within a relatively limited area (for example, a building). A LAN allows any connected device to interact with any other on the network. See also NetBIOS Extended User Interface (NetBEUI); network basic input/output system (NetBIOS); virtual local area network (VLAN); workgroup.

local group

A security group that can be granted rights and permissions on only resources on the computer on which the group is created. Local groups can have any user accounts that are local to the computer as members, as well as users, groups, and computers from a domain to which the computer belongs. See also global group; user account.

Local Security Authority (LSA)

A protected subsystem that authenticates and logs users on to the local system. In addition, the LSA maintains information about all aspects of local security on a system (collectively known as the local security policy), and provides various services for translation between names and identifiers.

local security policy

Security information about all aspects of local security on a system. The local security policy identifies who is assigned privileges and what security auditing is to be performed.

local user profile

A computer-based record about an authorized user that is created automatically on the computer the first time a user logs on to a workstation or server computer.

Localmon.dll

The standard print monitor for use with printers connected directly to your computer. If you add a printer to your computer using a serial or parallel port (such as COM1 or LPT1), this is the monitor that is used.

locator service

In a distributed system, a feature that allows a client to find a shared resource or server without providing an address or full name. Generally associated with Active Directory, which provides a locator service.

logical drive

A volume that you create within an extended partition on a basic master boot record (MBR) disk. Logical drives are similar to primary partitions, except that you are limited to four primary partitions per disk, whereas you can create an unlimited number of logical drives per disk. A logical drive can be formatted and assigned a drive letter. See also basic disk; basic volume; extended partition; master boot record (MBR); primary partition; volume.

logical printer

The software interface between the operating system and the printer in Windows. While a printer is the device that does the actual printing, a logical printer is its software interface on the print server. This software interface determines how a print job is processed and how it is routed to its destination (to a local or network port, to a file, or to a remote print share). When you print a document, it is spooled (or stored) on the logical printer before it is sent to the printer itself. See also printer.

logical volume

A volume created within an extended partition on a basic disk. You can format and assign a drive letter to a logical drive. Only basic disks can contain logical drives. A logical drive cannot span multiple disks. See also basic disk; extended partition; logical drive.

logon script

Files that can be assigned to user accounts. Typically a batch file, a logon script runs automatically every time the user logs on. It can be used to configure a user's working environment at every logon, and it allows an administrator to influence a user's environment without managing all aspects of it. A logon script can be assigned to one or more user accounts. See also user account.

long name

A folder name or file name longer than the 8.3 file name standard (up to eight characters followed by a period and an extension of up to three characters) of the FAT file system. This version of Windows supports long file names up to 255 characters. See also file allocation table (FAT); MS-DOS (Microsoft Disk Operating System).

loopback address

The address of the local computer used for routing outgoing packets back to the source computer. This address is used primarily for testing.
