gatekeeper

A server that uses a directory to perform name-to-IP address translation, admission control, and call management services in H.323 conferencing. See also H.323.

gateway

A device connected to multiple physical TCP/IP networks capable of routing or delivering IP packets between them. A gateway translates between different transport protocols or data formats (for example, IPX and IP) and is generally added to a network primarily for its translation ability.

In the context of interoperating with Novell NetWare networks, a gateway acts as a bridge between the server message block (SMB) protocol used by Windows networks and the NetWare Core Protocol (NCP) used by NetWare networks. A gateway is also called an IP router.

global group

A security or distribution group that can contain users, groups, and computers from its own domain as members. Global security groups can be granted rights and permissions on resources in any domain in its forest.

Global groups cannot be created or maintained on computers running Windows XP Professional. However, for Windows XP Professional-based computers that participate in a domain, domain global groups can be granted rights and permissions at those workstations and can become members of local groups at those workstations. See also group; local group; permission; user account.

globally unique identifier (GUID)

A 16-byte value generated from the unique identifier on a device, the current date and time, and a sequence number. A GUID is used to identify a particular device or component.

GPT

See definition for GUID partition table (GPT).

GPT disk

A disk that uses the GUID partition table (GPT) partition style. A partition style is the method that Windows XP uses to organize partitions on the disk. The GPT partition style supports volumes up to 18 exabytes and 128 partitions per disk. Only Itanium-based computers can use GPT disks. See also GUID partition table (GPT).

Graphical Identification and Authentication (GINA)

A DLL loaded during the Windows 2000 Winlogon process, which displays the standard logon dialog box and collects and processes user logon data for verification. See also dynamic-link library (DLL).

graphical user interface (GUI)

A display format, like that of Windows, that represents a program's functions with graphic images such as buttons and icons. GUIs allow a user to perform operations and make choices by pointing and clicking with a mouse.

group

A collection of users, computers, contacts, and other groups. Groups can be used as security or as e-mail distribution collections. Distribution groups are used only for e-mail. Security groups are used both to grant access to resources and as e-mail distribution lists. See also domain; global group; local group.

group memberships

The groups to which a user account belongs. Permissions and rights granted to a group are also provided to its members. In most cases, the actions a user can perform in Windows are determined by the group memberships of the user account to which the user is logged on. See also group; user account.

Group Policy

The Microsoft Management Console (MMC) snap-in that is used to edit Group Policy objects.

Group Policy object

A collection of Group Policy settings. Group Policy objects are essentially the documents created by the Group Policy snap-in, a Windows tool. Group Policy objects are stored at the domain level, and they affect users and computers contained in sites, domains, and organizational units. In addition, each Windows computer has exactly one group of settings stored locally, called the local Group Policy object. See also Group Policy; object.

GUI mode

The portion of Setup that uses a graphical user interface (GUI).

GUID partition table (GPT)

A disk-partitioning scheme that is used by the Extensible Firmware Interface (EFI) in Itanium-based computers. GPT offers more advantages than master boot record (MBR) partitioning because it allows up to 128 partitions per disk, provides support for volumes up to 18 exabytes in size, allows primary and backup partition tables for redundancy, and supports unique disk and partition IDs (GUIDs). See also Extensible Firmware Interface (EFI); globally unique identifier (GUID); master boot record (MBR).
