Active Directory Sites Active Directory Sites Sites are defined by IP subnets that are  well- connected , which means that network  infrastructure between them is fast and reliable.  In most cases, an Active Directory site will map to  a single LAN. Multiple sites will be joined together by site links.  Intersite replication takes place along site links  that you defined within Active Directory Sites  and Services.

Sites Sites When clients log on to Active Directory,  they use DNS to query the Active  Directory site topology to locate the  closest available domain controller and  other network resources.   Domain controllers use the site topology to  establish replication partners that provide  efficiency and keep the Active Directory  database consistent.

Default-First-Site-Name Default-First-Site-Name When you install the forest root domain  controller in an Active Directory forest, the  Active Directory Installation Wizard  creates a single site called Default-First- Site-Name. The forest root domain controller server  object is placed within the Servers folder  of this site.  The site can be renamed to more  accurately reflect a physical location.

Active Directory Replication Active Directory Replication The process of duplicating Active Directory  information between domain controllers for the  purposes of fault tolerance and redundancy. Based on a multimaster replication model, in  which the domain controllers from each domain  participate in the replication process for that  domain. They also replicates forest-wide schema and  configuration information.  Active Directory sites are the means by which  administrators can control replication traffic.
