6.1.1.2.2.1 Site Object
A site object corresponds to a set of one or more IP subnets that have LAN connectivity. Thus, by virtue of their subnet associations, DCs that are in the same site are well connected in terms of speed. Each site object has a child nTDSSiteSettings object and a Servers container.
parent: Sites container
objectClass: site
systemFlags: { FLAG_CONFIG_ALLOW_RENAME | FLAG_DISALLOW_MOVE_ON_DELETE }
Note The initial AD DS and AD LDS configuration contains one initial site object named Default-First-Site-Name, which has no subnet association.
