Introduction to AD [Active Directory] tutorials

  • LAN provided services to users and computer throughout the small network of computers from 5 to 50 PCs. Later LAN begin to grow into WAN, no of computer rose to thousands of computers. This made administration rather difficult as one had to manually synchronize the password and other security on all servers.

  • In 1993 university of Missigen created LDAP (Lightweight Directory Access Protocol) standard. Active Directory is based on the LDAP

  • AD is Directory Services for Windows 2000/2003 & is used to Authenticate and Authorize access to resources

  • Directory service provide way to Find, Secure & Access information about organization resources such as User, Group, Computer, Printer and other detail.

  • It stores it as database that holds above information

  • It allows Centralize administration & even Decentralize management if required.

  • It offers SSO (Single Sign On) capabilities so user can access computer throughout the enterprise without creating new user a/c on each computer

  • AD uses DNS for locating and naming objects. DNS names are easy to understand and match the naming system on the internet rather then remembering IP address.

Difference between WORKGROUP & DOMAIN

 

WORKGROUP

DOMAIN

: :

SAMIR SUS BOB

: : :

SAMIR,SUS,BOB

Here SAMIR cant start 2nd or 3rd PC, same way SUS cant start 1st or 3rd Pcetc

To use another Pc, his/her user name has to be created on ALL Pcs

All use a/c are stored on Domain controller here any user can logon to any Pc that are connected within domain

Username & Password is Authenticated By SAM (Security Accounts Manager)

Username & Password is Authenticated by AD (Active Directory) which is stored on DC (Domain Controller). When we install Domain Controller, SAM is migrated to AD

No Centralization management,

Easy to manage

Centralized Management

Complex, need Domain Administrator

 

Structure & Relationship of Active Directory

 

FOREST

TREE

DOMAIN

ORGANIZATION UNIT

 

Pre-requisite for Domain Controller

  • DNS must be available on the network before you can install a Domain controller in a new domain. AD uses DNS for locating and naming objects.

  • NTFS - (HDD must have NTFS File System)

  • NIC (LAN card with IP Address)

FOREST

  • A forest can either consist of a single tree or number of trees that do not share a contiguous namespace. In this arrangement, every tree root domain has a transitive trust relationship with the root domain.

  • Groups of domain tree are grouped together to share resources.

  • Forest container can contain TREES, DOMAINS & OUs.

  • The Forest root domain is the first Domain created in Active Directory forest.

  • The first domain controller installed in the forest automatically becomes the global catalog server for that domain.

TREE

  • A tree is a hierarchical arrangement of Windows Server 2003 domains that share a contiguous namespace. In such an arrangement the root domain name is attached as a suffix to the new domain names.

  • We can say Tree is a group of domains based on same namespace.

  • Tree container can contain Domains and OUs.

  • The Tree root domain is the highest Active Directory domain in the tree. The root domain contains the configuration and schema data for the tree.

  • The new domain is called a child domain of an existing parent domain and has a two-way, transitive trust relationship with its parent domain.

  • Thus, a domain tree structure is formed by adding child domains to the root domain.

  • All domains in a tree

  • Are connected with two-way transitive trusts

  • Share the same schema

  • Have common global catalogs

DOMAIN

  • In Windows Server 2003, a Domain is a logical grouping of network elements, including computers, users, printers & other components that make up the network.

  • Domain container object can contain Child Domain, OUs container and other leaf objects such as Users, Group, Computers, Printer etc.

  • Between Parent Domain and Child Domain there exist two way transitive trust.

  • Domain that uses Active Directory are referred as Active Directory Domains or Domain Controller.

  • In an Active Directory domain, any member server can be promoted to a DC - Domain controller by installing AD using DCPROMO command.

  • Similarly you can demote DC (Domain Controller) by removing AD on the server by issuing DCPROMO command.

  • Although you can deploy Active Directory domain with only one DC - Domain Controller, one may deploy multiple DC called ADC (Additional Domain Controller) to ensure availability of directory services and logon authentication in case if one or more DC fail.

  • It is graphically represented by Triangle

OU (Organization Unit)

  • It can be created based on location, department or business purpose.

  • OU is used for administrative control

  • OU is the smallest container on which one can assign GPOs Group Policies Object.

  • You can not assign Share Permission or Security rights to OU.

  • OUs container can contain child OUs and other leaf objects such as Users, Groups, Computers, Printers etc.

Other Servers

  • Stand-Alone Servers In Windows Server 2003, a stand-alone server is a Server computer that does not have Active Directory installed on it and does not belong to a domain. It might serve some other server role like DHCP, PRINTER, DNS, APPLICATION etc.

  • Member Server In Windows Server 2003, a member server is a Server computer that belongs to a domain but does not have Active Directory installed on it. Once Active Directory is installed on a member server, it ceases to be a member server and becomes a DC Domain Controller.
