Term
Fault tolerance

Capable of responding gracefully to a software or hardware failure
Term
Read-Only Domain Controller
Definition
domain controller that contains a copy of the ntds.dit file that cannot be modified and that does not replicate its changes to other domain controllers within Active Directory
Term
Publishing
Definition
Object allows users to acces network resources by searching the Active Directory database for the desired resources
Term
Container Object
Definition
Can have other objects housed within it
Term
Leaf Object
Definition
cannot contain other objects and usually refers to a resource such as a printer, folder, user or group
Term
Partitions
Definition
Active Directory divides information
Term
Naming Context (NC's)
Definition

Term
Schema NC
Definition
conatins the rules and defintions that are used for creating and modifying object classes and attributes within active directory
Term
Configuration NC
Definition
contains information regarding the physical topology of the network as well as other configuration data that must be replicated throughout the forest
Term
Domain NC
Definition
Consist of user, computer, and other resource information for a particular Active Directory domain
Term
Domain tree
Definition

Term
Organizational Unit (OU)

Term
Delegation
Definition
Administrastion OU's also can be delegated to a departmental supervisor or manager and thus can allow that person to manage day to day resource or more mundane tasks such as resetting passwords

Every resource in Active Directory
Term
attributes schema
Definition
Is a master database that conatins definitions of all objects in Active Directory
Term

Definition
Identifies the object in the database it is given when it is first created
Term
Globally Unique Identifier (GUID)

Information that is not critical to know but good to know

Definition
automatically contains and maintains the replication topology
Term
Distinguished Name (DN)
Definition
references an object to Active Directory directory structure using its entire hierachal path starting with the object itself and including all parent objects up to the root of the domain
Term
IP addresses

Term
Locator service
Definition
provides direction for clients that need to know which server does what function
Term

Term
Windows 2000 native
Definition
allows backward compatability with Microsoft Windows 2000
Term
Windows Server 2003
Definition
function level allows Windows Server 2003 and Server 2008 domain controllers only
Term
Trust Relationships
Definition
To allow access between multiple domains and/or forests either within a single forest or across multiple enterprise networks
Term
shortcut trust
Definition
If the domains within a forest are seperated by slow WAN links and this tree walking process takes an exceedingly long time to allow user authentication across domains
Term
external trust
Definition
are one way non-transitive trusts
