start saying that in of Microsoft server technologies, Windows 2003 has a very strong way to authenticate users within a weel or business network and makes it through Active Directory or Active Directory (AD), which in turn works under domain concepts and relying on the DNS service.
For these effects in Windows 2003 Server environments, which are defined domain, Trees and Forests; details below those that are exposed to examples
DOMAIN .- It is a region, sphere, grouping or defined area of \u200b\u200bdomain objects and that is comprised of domain controllers, computers, users, organizational units and groups.
This region or area, access is defined, its policies, ratings and restriccions on them. The team that has full control of all these elements within the domain, the domain controller.
TREE .- It occurs when a domain root, or first domain, in turn has children subdomains or domains. All of these groups that break off the root domain would form a tree. Understand that each domain or subdomain has its own DC (Domain Controller). 
FOREST .- It's when there are multiple domain trees is say that the whole domain tree in an organization is denomima FOREST.
Domain Control .- is the team that is responsible for controlling all access, permits, authorizations, policies, configurations, etc. domain of objects within a specific domain.
domain objects .- It is said of the elements of a domain and are Domain Controllers, Computers, Users, Groups and Organizational Units.
examples presented above in our names or initials are in English so tnemos:
DC = Domain Controller, Domain Controller
WKS = Workstations: Computer Users = users
OU = Organizational Unit: Organizational Units
In W2k3 technology, recently shown using the DNS server as a service for search and location of resources within a domain. so it is very important to its implementation and good setup for the domain controller can do its job.
also should be emphasized that another service that is still used is the WIN server, so that their implementation and configuration is needed, because the stations of Windows XP and earlier versions use it. Recently in the versions of Windows Vista and Windows 2008 Server dispenses with this service.
defined these concepts we turn to the parts of implementation and configuration of the respective services. We
narrow here that this blog is dedicated primarily to practical implementations of the different services of Windows 2003 Server, so that other theoretical concepts and deepening the existing track references like TechNet or the Microsoft Technical Reference.
