In which hierarchy ad forest is built

As the table above illustrates, a group can be a member of another group; this process is called nesting. Nesting helps you better manage and administer your environment based on business roles, functions and management rules.

Active Directory security groups and AD distribution groups are different things. For example, you can use security groups to assign permissions to shared resources and Active Directory distribution groups to create e-mail distribution lists in an Exchange environment. The technology is that when a user "logs on" to a computer, the machine creates the user's "access token".

SIDs of distribution groups are not included. To make it simple - you cannot assign permissions to distribution groups and even if you do so this would make no effect at all.

In a multiple-regional-domain environment in which a dedicated forest root is used, the replication of the forest root domain has minimal impact on the network infrastructure. This is because the forest root only hosts the service administrator accounts.

The majority of the user accounts in the forest and other domain-specific data are stored in the regional domains. One disadvantage to using a dedicated forest root domain is that it creates additional management overhead to support the additional domain.

If you choose not to deploy a dedicated forest root domain, you must select a regional domain to function as the forest root domain.

This domain is the parent domain of all of the other regional domains and will be the first domain that you deploy. The forest root domain contains user accounts and is managed in the same way that the other regional domains are managed. The primary difference is that it also includes the Enterprise Admins and Schema Admins groups.

The advantage of selecting a regional domain to function as the forest root domain is that it does not create the additional management overhead that maintaining an additional domain creates. Select an appropriate regional domain to be the forest root, such as the domain that represents your headquarters or the region that has the fastest network connections. If it is difficult for your organization to select a regional domain to be the forest root domain, you can choose to use a dedicated forest root model instead.

The forest root domain name is also the name of the forest. For example, an organization might have the forest root name corp. In this example, corp is the prefix and contoso. Select the suffix from a list of existing names on your network. In order for you to decide whether to create multiple domains and how to use them to best effect, you need to have a clear understanding of the relationship between trees and forests-known as a trust relationship.

The Slide show below will explain to you the workings of the trust relationship. While forests, trees, domains are all logical grouping of objects, the physical grouping of objects is made possible using a site. A site group objects based on IP addresses. Hence it cannot span across different physical locations. For example, if there are various branches of your organization located at different places, each location can be identified using a site.

A site is mainly used for replication and traffic control purposes. It is important to understand that site and domains are not interrelated. A site can contain multiple domains and a single domain could span across multiple sites. I hope you found this blog post helpful.

There are some considerations to make if you decide to add another forest to your AD schema:. A single AD forest is a simpler solution long-term and generally considered best practice. Multi-forests do provide an extra layer of security across the two domains, but at a significant increase to IT cost.

Multi-forests do not make you more secure by default. Every Active Directory has at least one AD forest, and there are cases where multiple AD forests are required to meet business and security objectives.
