What is Active Directory and what is the use of it

Active directory is a directory service, which maintains the relation ship between resources and enabling them to work together. Because of AD hierarchal structure windows 2000 is more calable, reliable. Active directory is derived from X.500 standards where information is stored is hierarchal tree like structure. Active directory depends on two Internet standards one is DNS and other is LDAP.Information in Active directory can be queried by using LDAP protocol

If you are a computer administrator for a large corporation or organization, you can easily update all end users computers with new software, patches and files simply by updating one object in a forest or tree.

Because each object fits into a set schema and has specific attributes, a network administrator can easily clear a person on a set tree or instantly give or deny access to select users for certain applications. The Microsoft servers use trust to determine whether or not access should be allowed. Two types of trusts that Microsoft active directories incorporate are transitive trusts and one way non transitive trusts. A transitive trust is when there is a trust that goes further than two domains in a set tree, meaning two entities are able to access each other's domains and trees.

A one way transitive trust is when a user is allowed access to another tree or domain; however, the other domain does not allow access to the further domains. This can be summed up as a network administrator and end user. The network administrator can access most trees in the forest including a specific end user's domain. However, the end user, while able to access his or her own domain, cannot access other trees.
