Your company has a main office and a branch office. The main office contains two domain controllers. You create an Active Directory site named BranchOfficeSite. You deploy a domain controller in the branch office, and then add the domain controller to the BranchOfficeSite site. You discover that users in the branch office are randomly authenticated by either the domain controller in the branch office or the domain controllers in the main office.
