Each has a contiguous namespace because each domain in the hierarchy is directly related to the domains above and below it in each tree. The forest has a discontiguous namespace because it contains two unrelated top-level domains. Forest and Domain Functional Levels Functional levels are a mechanism that Microsoft uses to remove obsolete backward compatibility within the Active Directory. It is a feature that helps improve performance and security. In Windows 2000 each domain had two functional levels which were called modes native mode and mixed mode while the forest only had one functional level. In Windows Server 2003 there are two more levels to consider in both domains and forests. To enable all Windows Server 2003 forest and domainwide features all DCs must be running Windows Server 2003 and the functional levels must be set to Windows Server summarizes the levels DCs supported in each level and each level s primary purpose.
