Active Directory Basics

Active Directory Directory Service (AD DS)
Houses information about all network resources:
  • Servers, printers, user accounts, groups of user accounts, security policies, and other information
  • Central listing of network resources
  • Quick access to network resources

Domain controllers (DCs)
  • Servers that have the AD DS server role installed
  • A Domain can have multiple DCs for Fault Tolerance and Load Balancing


Member servers
Do not have AD installed (therefore they are not DCs)

Domain
  • Fundamental component or container
  • Holds information about all network resources that are grouped within the domain (ie, all user accounts in the domain and all LAN Printers)
  • Each DC is equal to every other DC
  • Each DC has a full list of all networks resources in the domain
Multimaster Replication
  • Object defined in the DC are replicated between DCs
  • The volume of information to be replicated can be limited if required. This is a good option for slow links
  • Advantage : If one DC goes down, no network interruption
