The changes done to an object are replicated to all the DCs in th domain.Th infrastructure master and GC are updated with change in objects attribute with help of timpstamp and usn number which is incremented each time a change happens and information is replicated to all DCs .during replication the dcs compare the time stamp and usn number if the value is higher on DC2 then the DC 2 will initiate the replication to all other DCs.

What is directory schema?
The Active Directory schema defines the kinds of objects, the types of information about those objects, and the default security configuration for those objects that can be stored in Active Directory. The Active Directory schema contains the formal definitions of all objects, such as users, computers, and printers that are stored in Active Directory. On domain controllers running either Windows 2000 or Windows Server 2003, there is only one schema for an entire forest. This way, all objects that are created in Active Directory conform to the same rules. The schema has two types of definitions: object classes and attributes. Object classes such as user, computer, and printer describe the possible directory objects that you can create. Each object class is a collection of attributes. Attributes are defined separately from object classes. Each attribute is defined only once and can be used in multiple object classes. For example, the Description attribute is used in many object classes, but is defined only once in the schema to ensure consistency.

The Windows 2000 Active Directory is stored in what three files?
The Active Directory ESE database, NTDS.DIT, consists of the following tables: * Schema tablethe types of objects that can be created in the Active Directory, relationships between them, and the optional and mandatory attributes on each type of object. This table is fairly static and much smaller than the data table. * Link tablecontains linked attributes, which contain values referring to other objects in the Active Directory. Take the MemberOf attribute on a user object. That attribute contains values that reference groups to which the user belongs. This is also far smaller than the data table. * Data tableusers, groups, application-specific data, and any other data stored in the Active Directory. The data table can be thought of as having rows where each row represents an instance of an object such as a user, and columns where each column represents an attribute in the schema such as GivenName.
