3. Active Directory site and Service
The Active Directory Sites and Services snap-in is a GUI tool that allows IT network
administrators to configure Active Directory as a distributed network service
4. Active Directory Replication
Active Directory replication is the method of transferring and
updating Active Directory objects from one DC to another DC. Replication Component
‐ Knowledge Consistency
Checker (KCC)
‐ Directory System Agent (DSA)
‐ Extensible Storage Engine
(ESE)
‐ Remote Procedure Call (RPC)
‐ Inter-Site Topology Generator
(ISTG)
6. Active Directory Intra Site Replication
In an intrasite environment,
directory replication is
automatic.
Intrasite Replication
The bridgehead server is a domain
controller that you designate to
send and receive replicated data at
each site. The bridgehead server
from the originating site collects all
of the replication changes and then
sends them to the receiving site's
bridgehead server, which replicates
the changes to all domain
controllers in the site.
7. Active Directory Inter Site Replication
Intersite
If active directory infrastructure contains
more than one site, a change happens in
one site need to replicate over to other
sites. This is called as inter-site replication
and its topology is different from the intra-site
replication.
8. Understanding Domain and Trust
An Active Directory trust (AD trust) is a method of connecting two
distinct Active Directory domains (or forests) to allow users in one
domain to authenticate against resources in the other.
‒ Transitive Trusts
‒ Explicit Trusts
‒ Shortcut trust
9. Transitive Trust
Two-way transitive trusts are automatically established upon the
creation of a subdomain or with the addition of a domain tree into
an AD DS forest
10. Expicit Trust
explicitly transitive (between two forest) created trust between two
forest root domains. Forest trust are manually created, one-way
transitive or two-way transitive trust that allows you to provide
access to the resource between multiple forest.
11. Shortcut Trust
Shortcut trusts simply allow authentication verifications to be
processed faster, as opposed to having to move up and down a
domain tree.

13. Replication Interval active directoryR
The default replication interval is 180 minutes, or 3
hours. The minimum interval is 15 minutes. Consider the
following criteria to determine how often replication
occurs within the schedule window: A small interval
decreases latency but increases the amount of wide
area network (WAN) traffic
