WD Lesson-19

Configuring Sites

Sites define sets of Domain Controllers that are well connected in terms of speed and cost.

           Domain Controllers in the same site replicate on the basis of notification, when a DC has changes, it notifies its replication parenthesis.

            A site is the equivalent of a set of one or more IP subnets.

• When we install Active Directory on the first domain controller in a domain, a site object named Default-First-Site-Name is created in the sites container. It is necessary to install first domain controller into this site.
• When our first domain controller has been installed we can rename Default-First-Site-Name to the name we want to use for the site.

What is Subnet?

Computers on TCP/IP networks are assigned to sites based on their location in a subnet or a set of subnets. Subnets group computers in a way that identifies their feasible physical proximity on the network.

            Subnet information is used to find a domain controller in the same site as the computer that is authenticated during the logon process, and is used during Active Directory replication to determine the best routes between domain controllers.

How to create a subnet?

1. Click Start, point to Administrative Tools, and then click Active Directory Sites And Services.

2. Double-click the Sites folder.

3. Right-click the Subnets folder, and then click New Subnet.

4. In the New Object–Subnet dialog box, enter the subnet address in the Address box. In the Mask box, type the subnet mask that describes the range of addresses included in this site’s subnet. Choose a site to associate this subnet with, and then click OK.
