This policy setting specifies the Active Directory site to which computers belong. An Active Directory site is one or more well-connected TCP/IP subnets that allow administrators to configure Active Directory access and replication. To specify the site name for this setting click Enabled and then enter the site name. When the site to which a computer belongs is not specified the computer automatically discovers its site from Active Directory. If you do not configure this policy setting it is not applied to any computers and computers use their local configuration.
