IF the 2 domains does not have trusting between them, then we can have same named user and can use the same password.it does not concern any one in two domains
IF the 2 domains have trust relation between them then only one password will work for both
so it does not require two passwords
No need for different password. The user can be authenticated with the same password for the DCs of a domain.
The Active Directory administrative tools can only be used from a computer with access to a domain. The following Active Directory administrative tools are available on the Administrative Tools menu: Active Directory Users and Computers (dsa.msc) Active Directory Domains and Trusts (domain.msc) Active Directory Sites and Services (dssite.msc)
Administrative domain.
the centralized directory database in the domain model is NTDS.DIT(directory information tree) but for the local sstem not connected to domain is SAM
, the server hosting the replica of Active Directory database is called Domain Controller. In it's database is all information about all objects, that exist in particular Active Directory domain.
Active Directory
*Schema NC, *Configuration NC, * Domain NC Schema NC This NC is replicated to every other domain controller in the forest. It contains information about the Active Directory schema, which in turn defines the different object classes and attributes within Active Directory. Configuration NC Also replicated to every other DC in the forest, this NC contains forest-wide configuration information pertaining to the physical layout of Active Directory, as well as information about display specifiers and forest-wide Active Directory quotas. Domain NC This NC is replicated to every other DC within a single Active Directory domain. This is the NC that contains the most commonly-accessed Active Directory data: the actual users, groups, computers, and other objects that reside within a particular Active Directory domain
Active Directory NC (Naming Context's) * Active Directory consists of three partitions or naming contexts (NC) ** Domain, Configuration and Schema Naming Contexts * Each are replicated independently * An Active Directory forest has single schema and configuration ** Every domain controller (DC) holds a copy of each (schema, configuration NC's) * Forest can have multiple domains ** Every domain controller in a domain holds a copy of the domain NC
No, you do not. You only install Active Directory if the system is going to be a domain controller. If it is a member server or a standalone server Active Directory should not be installed.
DomainDNSzones
The Restartable Active Directory, that allows you to have the ntds.dit in offline mode WITHOUT rebooting the domain controller.
Domain controller is the physical object.
