Display the applications that use site knowledge.( Note: Although you can also manually add servers, the task of adding a server is typically performed automatically during Domain Controller setup.) You can delete or move servers between sites. Display the servers that participate in a site.As an example, Default-First-Site might be a site name such as Headquarters. Display the valid sites within an enterprise.The replication topology of sites on your network controls: You can rename this site later or leave it as is. The resulting first site is called Default-First-Site.
Your first site was set up automatically when you installed Windows 2000 Server on the first domain controller in your enterprise. As such, the mechanism for inter-site (between site) replication permits the selection of alternative transports, and is established by creating Site Links and Site Link Bridges. Replication between sites is assumed to occur on either higher cost or slower speed connections. An administrator can establish additional connection objects or remove connection objects, but at any point where replication within a site becomes impossible or has a single point of failure, the KCC steps in and establishes as many new connection objects as necessary to resume Active Directory replication. These are known as Active Directory connection objects. To ensure that the Active Directory service in the Windows 2000 operating system can replicate properly, a service known as the Knowledge Consistency Checker (KCC) runs on all DCs and automatically establishes connections between individual computers in the same site. For example, a workstation will select a DC within its site with which to authenticate. Sites control replication of your domain information and help to determine resource proximity. Sites are not part of your domain namespace. Because sites control how replication occurs, changes made with the Sites and Service snap-in affect how efficiently domain controllers (DC) within a domain (but separated by great distances) can communicate.Ī site is separate in concept from Windows 2000-based domains because a site may span multiple domains, and a domain may span multiple sites. Guide to Active Directory Sites and Services SitesĪ site is a region of your network with high bandwidth connectivity, and by definition is a collection of well-connected computers-based on Internet Protocol (IP) subnets. | Database | Virtualization | Knowledge Base | Contact Us | Windows | Network | Interview Questions Step-by-Step Guide to Active Directory Sites and Services
