W2000 by George Hernandez

Active Directory domains. Aka W2000 domains. Used by networks administered by a Windows 2000 Server.

In a pure W2000 domain, computers are identified by Active Directory object, IP address. A DNS is required but WINS is not.
In a mixed W200 domain, computers are identified by Active Directory object, IP address, and NetBIOS name. A DNS and WINS are required.
Active Directory objects mirror the DNS hierarchy but occupy separate namespaces. Both are mapped to the flat NetBIOS namespace as necessary.

Note that the left most item of a DNS name can be a computer, but the Active Directory hierarchy tree only contains domains. Note also that TLDs are outside of the Active Directory although they appear as part of a domain name. EG: Everything after "comp" is a tree:

comp.SubSubDomain.SubDomain.Domain.com

A forest is a collection of trees organized as peers and connected by two-way transitive trust relationships. Transitive means that if domain A trusts domain B, then domain A trusts all the domains that domain B trusts. The first tree created in the forest is the forest root domain.
