A directory service or name service, maps the names of network resources to their respective network addresses. With the name service type of directory, a user does not have to remember the physical address of a network resource; providing a name locates the resource. Each resource on the network is considered an object on the directory server. Information about a particular resource is stored as attributes of that object. Information within objects can be made secure so that only users with the available permissions are able to access it. More sophisticated directories are designed with namespaces as Subscribers, Services, Devices, Entitlements, Preferences, Content and so on. This design process is highly related to Identity management.
A directory service defines the namespace for the network. A namespace in this context is the term that is used to hold one or more objects as named entries. The directory design process normally has a set of rules that determine how network resources are named and identified. The rules specify that the names be unique and unambiguous. In X.500 (the directory service standards) and LDAP the name is called the Distinguished name (DN) and refers to a collection of attributes (relative distinguished names) that make up the name of a directory entry.
Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was only in charge of centralized domain management. Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services.
A server running Active Directory Domain Services (AD DS) is called a domain controller. It authenticates and authorizes all users and computers in a Windows domain type network—assigning and enforcing security policies for all computers and installing or updating software. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted password and determines whether the user is a system administrator or normal user.
Active Directory uses Lightweight Directory Access Protocol (LDAP) versions 2 and 3, Microsoft's version of Kerberos, and DNS.
Windows Server is a brand name for a group of server operating systems released by Microsoft. It includes all Windows operating systems branded "Windows Server", but not any other Microsoft product. The first Windows server edition to be released under that brand was Windows Server 2003. However, the first server edition of Windows was Windows NT 3.1 Advanced Server, followed by Windows NT 3.5 Server, Windows NT 4.0 Server, and Windows 2000 Server; the latter was the first server edition to include Active Directory, DNS Server, DHCP Server, Group Policy, as well as many other popular features used today.
This brand includes the following operating systems:
Microsoft has also produced Windows Server Essentials (formerly Windows Small Business Server) and Windows Essential Business Server (discontinued), software bundles which includes a Windows Server operating system and some other Microsoft Servers products.
Directory may refer to:
On Microsoft Servers, a domain controller (DC) is a server that responds to security authentication requests (logging in, checking permissions, etc.) within a Windows domain. A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
With Windows NT server, one domain controller per domain was configured as the Primary Domain Controller (PDC); all other domain controllers were Backup Domain Controllers (BDC).
Because of the critical nature of the PDC, best practices dictated that the PDC should be dedicated solely to domain services, and not used for file/print/application services that could slow down or crash the system. Some network administrators took the additional step of having a dedicated BDC online for the express purpose of being available for promotion if the PDC failed.
A BDC could authenticate the users in a domain, but all updates to the domain (new users, changed passwords, group membership, etc.) could only be made via the PDC, which would then propagate these changes to all BDCs in the domain. If the PDC was unavailable (or unable to communicate with the user requesting the change), the update would fail. If the PDC was permanently unavailable (e.g. if the machine failed), an existing BDC could be promoted to be a PDC.

Active Directory is a system which offers centralized control of your computers. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for the rest of our always free training videos. This video looks at what Active Directory is and why you would use it. The video explains the difference between a workgroup and a domain so you can better understand when you would want to deploy Active Directory. Terminology used in the video Workgroup A workgroup is a network setup in which each computer on the network keeps its own store of user names and passwords. In order to access another computer on the network, you need to know a username and password on that computer. This does not scale well. The user will be prompted for a username and password when he or she accesses another ...
Enterprise IT runs on Microsoft's Active Directory Services. Managing roles, understanding the tools and functions of ADS, and being able to explain them is a common part of the interview process for an IT position in a large organization.

Lightweight Directory Services is a lightweight version of Active Directory Domain Services. This video provides an introduction to Lightweight Directory Services and what it can and cannot do. Download the PDF handout http://itfreetraining.com/handouts/adlds/adlds-intro.pdf AD LDS Active Directory Lightweight Directory Services (AD LDS) was originally a downloadable add-on to Windows Server called Active Directory Application Mode (ADAM). In Windows Server 2008 this became an additional role included in the operating system. AD LDS uses the same code as AD DS and thus provides some of the same functionality. As you will see, it provides a lot of the same functionality but is also flexible enough to offer additional options that are not possible using AD DS. AD LDS Example In this examp...

Class Notes DC's or Domain Controllers are the server that control the Active Directory Service Domains are made up of Domain Controllers and Member PC's and Servers. There can be multiple Domain Controllers in a Domain for fault Tolerance and Load Balancing. DC's keep data synchronized through replication. The schedule for replication is called the "replication strategy". DC's can be grouped into Sites. Sites are comprised of Domain Controllers located at the same ge...
