| Windows Server domain | A logical group of computers that share a central directory and user database. | All Windows NT-based versions | |
| Active Directory | AD | A set of technologies introduced with Windows 2000 that allows administrators to assign enterprise-wide policies, deploy programs to many computers, and apply critical updates to an entire organization.

Networks can vary from a small installation with a few objects, to global-scale directories with millions of objects.

| Domain controller | DC, PDC, BDC | A server that responds to security authentication requests (logging in, checking permissions, etc.) within a Windows Server domain. Prior to Windows 2000, a domain controller was either a Primary Domain Controller (PDC), of which there could only be one with this role; or a Backup Domain Controller (BDC). In Windows 2000 and later the concept of primary and secondary domain controllers were eliminated, partially to emphasize the multi-master replication technology available in Windows. | All Windows NT-based versions |
| Group Policy | GP, GPO | Provides centralized management of user and computer settings in an Active Directory environment. Group policy can control a target object's registry, NTFS security, audit and security policy, software installation, logon/logoff scripts, folder redirection, and Internet Explorer settings. Policy settings are stored in Group Policy Objects (GPOs), and may be linked to one or more sites, domains or organizational units. Related topics: Administrative Templates |

Famous quotes containing the words windows and/or components:
“All day long the machine waits: rooms,
stairs, carpets, furniture, people
those people who stand at the open windows like objects
waiting to topple.”

“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
