Default-first-site-name-in-DC

  • After you promote your first DC in the forest, the Default-First-Site-Name site is created.
  • All DCs in the forest are added to this site by default.
  • You should rename this site to something logical.
  • If you create multiple sites and assign subnets to the sites, when promoting a DC with an IP in a different site, then by default, the DC will be added to the proper site based on it’s IP.
