A record |
The building block of the DNS that maps a single IP address to a DNS hostname. |
|
Active Directory Lightweight Directory Services (AD LDS) |
Role that provides developers the ability to store data for directory-enabled applications without incurring the overhead of extending the Active Directory schema to support their applications. |
|
Admin Role Separation |
Feature offered by Read-Only Domain Controllers (RODCs) that enables an administrator to configure a user as the local administrator of a specific RODC without making the user a Domain Admins with far-reaching authority over all domain controllers in the entire domain and full access to the Active Directory domain data. |
|
aging |
The dynamic update feature that places a timestamp on record, based on the current server time, when the IP address is added. |
|
binaries |
The executable files needed to install Windows. |
|
dcpromo |
The Active Directory Installation Wizard |
|
Directory Services Restore Mode (DSRM) |
A special startup mode used to run an offline defragmentation. |
|
domain netBIOS name |
Domain name limited to 15 characters that is maintained for legacy compatibility with older applications that cannot use DNS for their name resolution. |
|
dynamic updates |
Enables the DNS database to be updated with the changed information when the Internet Protocol (IP) address of a host changes |
|
Flexible Single Master Operations (FSMO) |
The specific server roles that work together to enable the multimaster functionality of Active Directory |
|
forward lookup zone |
Zones necessary for computer hostname–to–IP address mappings, which are used for name resolution by a variety of services. |
|
fully qualified domain name (FQDN) |
The complete DNS name used to reference a host’s location in the DNS structure; for example, LUCERNEPUBLISHING |
|
global catalog |
A domain controller that contains a partial replica of every domain in Active Directory. It stores those attributes most frequently used in search operations and those attributes required to locate a full replica of the object. The Active Directory replication system builds this automatically. |
|
incremental zone transfers |
Method of conserving bandwidth by transferring part of a zone |
|
instance |
A single occurrence of an element |
|
latency |
The amount of time or delay it takes to replicate information throughout the network |
|
netdom |
A command-line tool that is used to create, delete, verify, and reset trust relationships from the Windows Server 2008 command line |
|
nslookup |
A command-line tool that is critical for working with DNS on Server Core |
|
Object Identifier (OID) |
A unique string used to identify every class or attribute added to a schema. OIDs must be globally unique, and they are represented by a hierarchical dotted-decimal notation string. |
|
Password Replication Policy |
A list of user or group accounts whose pass- words should or should not be stored on a particular Read-Only Domain Controller (RODC) |
|
pointer (PTR) |
The resource record that is the functional opposite of the A record, providing an IP address-to- name mapping for the system identified in the Name field using the in-addr.arpa domain name. |
|
priority |
A mechanism to set up load balancing between multiple servers that are advertising the same SRV records. |
|
restartable Active Directory |
Feature that enables administrators to place the NTDS.DIT file in an offline mode without rebooting the domain controller outright |
|
reverse lookup zone |
Zone that answers queries in which a client provides an IP address and DNS resolves the IP |
|
scavenging |
The process of removing records that were not refreshed or updated within specified time intervals |
|
Server Core |
A special installation option that creates a minimal environment for running only specific services and roles. This runs without the Windows Desktop shell and is administered exclusively from the command line or using Group Policy. |
|
Server Manager |
A utility that enables administrators to view any other roles the server might be performing. |
|
staged installation |
To begin the Active Directory installation at a central location, such as a data center, and then allow a local administrator to complete the configuration |
|
SYSVOL |
A shared folder that exists on all domain controllers and is used to store Group Policy Objects, login scripts, and other files that are repli- cated domain-wide |
|
time-to-live |
The length of time a record |
|
unattended installation |
Running dcpromo from the command line using a specially formatted text file to specify the necessary installation options |
|
User Principal Name (UPN) |
A naming format that simplifies access to mul- tiple services such as Active Directory and email. Follows the format: username@domainname |
|
weight |
A relative weighting for SRV records that have the same priority. |
|
zone transfers |
The process of replicating DNS information from one DNS server to another |
|
Service record (SRV record) |
A specification of data in the Domain Name System defining the location (the hostname and port number) of servers for specified services
Format: _[service]._[proto].[name]. [TTL] [class] [SRV] [priority] [weight] [port] [target].
Example: _sip._tcp.example.com. 86400 IN SRV 0 5 5060 sipserver.example.com. |
