What are the physical components of active directory?
The logical structure of active directory include forest, domains, tree, OUs and global catalogs.Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.Forest : Active directory forest as due to represents the external boundary of the directory service.These are two types of active directory forest :-I) Single Forest2) Multiple forest

What is single active directory?
Multiple Trees in a Single Forest Model(Single Active Directory)Let's say that your organization would like to look at Active Directory and wants to use an external namespace for your design. However, your environment currently uses multiple DNS namespaces and needs to integrate them into the same design. Contrary to popular misconception, integration of these namespaces into a single AD forest can be done through the use of multiple trees that exist in one forest. One of the most misunderstood characteristics of Active Directory is the difference between a contiguous forest and a contiguous DNS namespace. Many people do not realize that multiple DNS namespaces can be integrated into a single Active Directory forest as separate trees in the forest. For example, Figure 5.6 shows how Microsoft could theoretically organize several Active Directory domains that share the same forest but reside in different DNS namespaces.Figure 5.6 Sample Active Directory forest with multiple unique trees within the same forest.Only one domain in this design is the forest root, in this case microsoft.com, and only this domain controls access to the forest schema. All other domains, including subdomains of microsoft.comand the other domains that occupy different DNS structures, are members of the same forest. All trust relationships between the domains are transitive, and trusts flow from one domain to another.When to Choose a Multiple Tree Domain ModelIf your organization currently operates multiple units under separate DNS namespaces, one option may be to consider a design such as this one. It is important to understand, however, that simply using multiple DNS namespaces does not automatically qualify you as a candidate for this domain design. For example, you could own five separate DNS namespaces and instead decide to create an Active Directory structure based on a new namespace that is contiguous throughout your organization. Consolidating your Active Directory under this single domain could simplify the logical structure of your environment while keeping your DNS namespaces separate from Active Directory.If your organization makes extensive use of its separate namespaces, you may want to consider a design like this. Each domain tree in the forest can then maintain a certain degree of autonomy, both perceived and real. Often, this type of design will seek to satisfy even the most paranoid of branch office administrators who demand complete control over their entire IT structure.Real-World Design ExampleTo gain a greater understanding of the times an organization might use this particular design model, let's look at the following AD structure. City A is a local county governmental organization with a loose-knit network of semi-independent city offices such as the police and fire departments that are spread out around the city. Each department currently uses a DNS namespace for name resolution to all hosts and user accounts local to itself, which provides different e-mail addresses for users located in the fire department, police department, and other branches. The following namespaces are used within the city's infrastructure:citya.orgfiredeptcitya.orgpoliceofcitya.orgcityalibrary.orgThe decision was made to merge the existing network environments into a single Active Directory forest that will accommodate the existing departmental namespaces but maintain a common schema and forest root. To accomplish this, Active Directory was established with citya.org as the namespace for the root domain. The additional domains were added to the forest as separate trees but with a shared schema, as shown in Figure 5.7.Figure 5.7 Single Active Directory forest with separate directory trees for departments.The individual departments were able to maintain control over their individual security and are disallowed from making changes in domains outside their control. The common forest schema and global catalog helped to increase collaboration between the varying organizations and allow for a certain amount of central administration.This type of domain design is logically a bit messier but technically carries the same functionality as any other single forest design model. All the domains are set up with two-way transitive trusts to the root domain and share a common schema and global catalog. The difference lies in the fact that they all utilize separate DNS namespaces, a fact that must also be reflected in the zones that exist on your DNS server.This information is taken from following link:http://www.informit.com/articles/article.aspx?p=32080&seqNum=7.Best RegardsSheba Tasaduque
What is domain in active directory?
a domain as "a single security boundary of a Windows NT-based computer network. Active Directory is made up of one or more domains. On a standalone workstation, the domain is the computer itself. A domain can span more than one physical location. Every domain has its own security policies and security relationships with other domains. When multiple domains are connected by trust relationships and share a common schema, configuration, and global catalog, they constitute a domain tree. Multiple domain trees can be connected together to create a forest." Domain A Windows domain is a collection of security principals that share a central directory database. This central database (known as Active Directory starting with Windows 2000,[1] Active Directory Domain Services in Windows Server 2008 and Server 2008 R2, also referred to as NT Directory Services on Windows NT operating systems, or NTDS) contains the user accounts and security information for the resources in that domain. Each person who uses computers within a domain receives his or her own unique account, or user name. This account can then be assigned access to resources within the domain. In a domain, the directory resides on computers that are configured as "domain controllers." A domain controller is a server that manages all security-related aspects between user and domain interactions, centralizing security and administration. A Windows Server domain is generally suited for businesses and/or organizations when more than 10 PCs are in use.
Can you have two domains on server 2003?
You can't have two domains on the same server 2003 machine, since it has to manage a single domain. However, you can have many domains in a server 2003 forest or a series of trees, which are managed by a forest controller. And, a single server 2003 can manage multiple domains.

A Windows Server domain is generally suited for businesses and/or organizations when more than 10 PCs are in use. Trust To allow users in one domain to access resources in another, Active Directory uses trusts. Trusts inside a forest are automatically created when domains are created. The forest sets the default boundaries of trust, and implicit, transitive trust is automatic for all domains within a forest. Terminology One-way trust One domain allows access to users on another domain, but the other domain does not allow access to users on the first domain. Two-way trust Two domains allow access to users on both domains. Trusting domain The domain that allows access to users from a trusted domain. Trusted domain The domain that is trusted; whose users have access to the trusting domain. Transitive trust A trust that can extend beyond two domains to other trusted domains in the forest. Intransitive trust A one way trust that does not extend beyond two domains. Explicit trust A trust that an admin creates. It is not transitive and is one way only. Cross-link trust An explicit trust between domains in different trees or in the same tree when a descendant/ancestor (child/parent) relationship does not exist between the two domains. Shortcut Joins two domains in different trees, transitive, one- or two-way Forest Applies to the entire forest. Transitive, one- or two-way Realm Can be transitive or nontransitive, one- or two-way External Connect to other forests or non-AD domains. Nontransitive, one- or two-way.[18] Windows Server 2003 introduced the forest root trust. This trust can be used to connect Windows Server 2003 forests if they are operating at the 2003 forest functional level. Authentication across this type of trust is Kerberos based (as opposed to NTLM). Forest trusts are transitive for all the domains in the trusted forests. Forest trusts, however, are not transitive
What is active directory?
Active Directory in Windows Server 2003 The Active Directory is the one of the important part of Windows Server 2003 networking .First need to know and understand Active directory . How does it work? It makes information easy for the administrator and the users. You can use the Active Directory to design a organization's structure according to the requirement . If you are using the Active Directory then you can scale active directory from a single computer to a single network or to many networks. In active directory you can include every object server and domain in a network. Logical Component In the organization you set up in Windows Server 2003 and the organization you set up in Exchange Server 2003 are the same and the same is the case with Windows 2000 and Exchange 2000 as well. Now i am going to tell you it's advantage one user administrator manage all aspects of user configuration. These logical constructs which are described in the following subsections allow you to define and group resources so that they can be located and administered by the name rather than by physical location. Objects Object is the basic unit in the Active Directory. It is a apocarpous named set of features that represents something adjective such as a user , printer and the application. A user is also an object. In Exchange a user's features include its name and location , surrounded by other things. Organization Unit Organization Unit is a persona in which you can keep objects such as user accounts, groups, computer, printer . applications and other (OU). In organization unit you can assign specific permission to the user's. organization unit can also be used to create departmental limitation. Domains Domains is a group of computers and other resources that are part of a network and share a common directory database .Once a server has been installed , you can use the Active Directory Wizard to install Active Directory in order to install Active directory on the first server on the network , that server must have the access to a server running DNS (Domain Name Service). If you don't have install this service on your server then you will have to install this service during the Active Directory installation.. An active directory is a directory structure used on Microsoft Windows based computers and servers to store information and data about networks and domains. It is primarily used for online information and was originally created in 1996 and first used with Windows 2000. An active directory (sometimes referred to as an AD) does a variety of functions including the ability to provide information on objects, helps organize these objects for easy retrieval and access, allows access by end users and administrators and allows the administrator to set security up for the directory. An active directory can be defined as a hierarchical structure and this structure is usually broken up into three main categories, the resources which might include hardware such as printers, services for end users such as web email servers and objects which are the main functions of the domain and network. It is interesting to note the framework for the objects. Remember that an object can be a piece of hardware such as a printer, end user or security settings set by the administrator. These objects can hold other objects within their file structure. All objects have an ID, usually an object name (folder name). In addition to these objects being able to hold other objects, every object has its own attributes which allows it to be characterized by the information which it contains. Most IT professionals call these setting or characterizations schemas. Depending on the type of schema created for a folder, will ultimately determine how these objects are used. For instance, some objects with certain schemas can not be deleted, they can only be deactivated. Others types of schemas with certain attributes can be deleted entirely. For instance, a user object can be deleted, but the administrator object can not be deleted. When understanding active directories, it is important to know the framework that objects can be viewed at. In fact, an active directory can be viewed at either one of three levels, these levels are called forests, trees or domains. The highest structure is called the forest because you can see all objects included within the active directory. Within the Forest structure are trees, these structures usually hold one or more domains, going further down the structure of an active directory are single domains. To put the forest, trees and domains into perspective, consider the following example. A large organization has many dozens of users and processes. The forest might be the entire network of end users and specific computers at a set location. Within this forest directory are now trees that hold information on specific objects such as domain controllers, program data, system, etc. Within these objects are even more objects which can then be controlled and categorized.

What is the difference between the woods and forest?
Multiple domain models create logical structures called treeswhen they share contiguous DNS names. For example, contoso.com, us.contoso.com, and europe.contoso.com share contiguous DNS namespaces and would together be considered a tree. An Active Directory that consists of multiple trees is naturally called a forest. The forest is the largest structure in an Active Directory. When you promote the first domain controller on a Windows Server 2003 network, you create a forest, a tree within that forest, and a domain within that tree, all at the same time. A forest might contain multiple domains in multiple trees, or just one domain.
What is trees in active directory?
A TreeTrees are collections of one or more domains that allow global resource sharing. A tree may consist of a single domain or multiple domains in a contiguous namespace. Adding a domain to a tree becomes a child of the tree root domain. Domain will be called as parent domain to which child domain is attached. A child domain can also have its multiple child domains. Child domain uses the name followed by parent domain name and gets a unique Domain Name System (DNS).For example, if tech.com is the root domain, you can create one or more Child domains to tech.com such as north.tech.com and or south.tech.com. These "children" may also have child domains created under them, such as sales.north.tech.com.The domains in a tree have two-way, Kerberos transitive trust relationships. A Kerberos transitive trust simply means that if Domain A trusts Domain B and Domain B trusts Domain C, then Domain A trusts Domain C. Therefore, a domain joining a tree immediately has trust relationships established with every domain in the tree.
What is the primary distinction between an active directory tree and an active directory forest?
The Domain is the core unit of logical structure in Active Directory. All objects which shares a common directory database, trust relationship with other domain and security policies is known as Domain. Each domain stores information only about the objects that belong to that domain.All security polices and settings, such as administrative rights, security policies, and Access Control Lists (ACLs), do not cross from one domain to another, thus a domain administrator has full rights to set policies only within domain they belong to.Domains provide administrative boundaries for objects; manage security for shared resources and a unit of replication for objects.A TreeTrees are collections of one or more domains that allow global resource sharing. A tree may consist of a single domain or multiple domains in a contiguous namespace. Adding a domain to a tree becomes a child of the tree root domain. Domain will be called as parent domain to which child domain is attached. A child domain can also have its multiple child domains. Child domain uses the name followed by parent domain name and gets a unique Domain Name System (DNS).For example, if tech.com is the root domain, you can create one or more Child domains to tech.com such as north.tech.com and or south.tech.com. These "children" may also have child domains created under them, such as sales.north.tech.com.The domains in a tree have two-way, Kerberos transitive trust relationships. A Kerberos transitive trust simply means that if Domain A trusts Domain B and Domain B trusts Domain C, then Domain A trusts Domain C. Therefore, a domain joining a tree immediately has trust relationships established with every domain in the tree.A ForestA forest is a collection of multiple trees that share a common global catalog, directory schema, logical structure, and directory configuration. Forest has automatic two-way transitive trust relationships. The very first domain you create in the forest is called the forest root domain.Forests allow organizations to group their divisions which use different naming scheme, and may need to operate independently. But as an organization they want to communicate with the entire organization via transitive trusts, and share the same schema and configuration container.
