It refer to resources like:
Users
Computers
Printers
Objects
In a network environment, especially in Windows-based systems: _______ refer to resources while _________ are collections of objects
Objects and Groups
These are collections of objects used to:
Simplify permissions
Manage access control efficiently
Groups
Objects refer to resources like: (3)
Groups are collections of objects used to: (2)
These are structures used in directory services like Active Directory (3)
Domains
Trees
Forests
A collection of objects (users, computers) sharing a common database
Domain
A group of domains sharing a namespace
Tree
A collection of trees (largest structure)
Forest
It is used to resolve NetBIOS names into IP addresses.
Works like DNS but for older Windows systems
Uses LMHOSTS file if WINS server is unavailable
WINS (Windows Internet Name Service)
It automatically assigns IP addresses to devices on a network.
Eliminates manual IP configuration
Provides:
IP address
Subnet mask
Gateway
DNS
DHCP Services (Dynamic Host Configuration
Protocol)
Maps hostnames to IP addresses
Used for DNS resolution locally
Located in:C:\Windows\System32\drivers\etc\hosts
HOSTS File
Used for NetBIOS name resolution
Works with older Windows networking
Example: 192.168.1.10 LAB-PC-01 #PRE
Allows the system to recognize LAB-PC-01 without WINS
LMHOSTS File
It resolves domain names locally
HOSTS
It resolves NetBIOS names
LMHOSTS
It centralized NetBIOS name resolution
Automatic IP configuration
DHCP (Dynamic Host Configuration
Organize and manage network resources
Domains/Groups
It stores, organizes, and provides access to information in a directory. _______ are used for locating, managing, administering, and organizing common items and network resources, such as volumes, folders, files, printers, users, groups, devices, telephone numbers, and other objects.
Directory Service
It is a technology created by Microsoft that provides a variety of network services, including the following:
LDAP
Kerberos-based and single sign-on authentication
DNS-based naming and other network information
A central location for network administration and delegation of authority
Active Directory
It is an application protocol for querying and modifying data using directory services running over TCP/IP. Within the directory, the sets of objects are organized in a logical hierarchical manner so that you can easily find and manage them.
LDAP (Lightweight Directory Access Protocol)
It is a computer network authentication protocol, which allows hosts to prove their identity over a nonsecure network in a secure manner. It can also provide mutual authentication so that both the user and server verify each other’s identity.
Kerberos
It allows you to log on once and access multiple related but independent software systems without having to log in again. As you log on with Windows using Active Directory, you are assigned a token, which can then be used to sign on to other systems automatically.
Sigle Sign-On (SSO)
These are logical representations of your network organization, which allow you to organize them in the best way to manage them. To identify these, Active Directory is closely tied to DNS.
Domains, Trees, and Forests
Without ________ records, Active Directory will not be able to function properly.
DNS and SRV
It is made of one or more domains (although most people think of a ______ as two or more domains) with contiguous name space.
It is made of one or more trees (although most people think of a _______ as two or more trees). It differs from a tree because it uses disjointed namespaces between the trees.
It is one or more IP subnets that are connected by a high-speed link, typically defined by a geographical location. For example, say you have a four-story office building. Although the building includes several subnets, all of the computers within the building use layer-2 and layer-3 switches to communicate with each other.
Site
It is a Windows server that stores a replica of the account and security information for the domain and defines the domain boundaries. To make a computer running Windows Server 2008 a domain controller, you must install the Active Directory Domain Services and execute the dcpromo (short for dc promotion) command.
Domain Controller
After you have promoted a computer to a domain controller, you can use several MMC snap-in consoles to manage Active Directory. These consoles are as follows (3)
Active Directory Users and Computers
Active Directory Domains and Trusts
Active Directory Sites and Services
Used to manage users, groups, computers, and organizational units.
Used to administer domain trusts, domain and forest functional levels, and user principal name (UPN) suffixes.
Used to administer replication of directory data among all sites in an Active Directory Domain Services
What is the best way to assign users to manage other users and computers in Active Directory?
Organizational Units
To help organize objects within a domain and minimize the number of domains you require, you can use ________, commonly known as ___. It can be used to hold users, groups, computers, and other organizational units.
Organizational Units (OUs)
An _____ is a distinct, named set of attributes or characteristics that represent a network resource. Common _______ used within Active Directory are computers, users, groups, and printers.
Object
Active Directory objects are assigned a 128-bit unique number called a ________, sometimes referred to as a security identifier (SID), to uniquely identify an object.
Globally Unique Identifier (GUID)
A ________ enables a user to log on to a computer and domain. As a result, it can be used to prove the identity of a user, and this identity information can then be used to determine what the user can access and what kind of authorization he or she has.
User Account
It allows users to log on and access resources on the computer in which the account was created. It is stored in the Security Account Manager (SAM) database on the local computer.
Local User Account
It is stored on the domain controller and allows you to gain access to resources within the domain, assuming you have been granted permissions to access those objects.
Domain User Accounts
