What is responsible for generating the Active Directory replication topology?

What is responsible for generating the Active Directory replication topology?

The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite).

How is replication topology generated?

To generate a replication topology automatically, the KCC evaluates information in the configuration partition on sites, the cost of sending data between these sites (cost refers to the relative value of the replication paths), any existing connection objects, and the replication protocols that the KCC can use between …

How do you check replication topology?

How to check if domain controllers are in sync with each other?

  1. Step 1 – Check the replication health.
  2. Step 2 – Check the inbound replication requests that are queued.
  3. Step 3 – Check the replication status.
  4. Step 4 – Synchronize replication between replication partners.
  5. Step 5 – Force the KCC to recalculate the topology.

What is replication topology?

Creating Replication Topology Active Directory replication is a one-way pull replication whereby the DC that needs updates (the target DC) gets in touch with the replication partner (the source DC). Then, the source DC selects the updates that the target DC needs, and copies them to the target DC.

Which ad component is responsible for AD replication?

The ISTG is a component of the KCC that runs on one DC in each AD site and is responsible for creating connection objects for replication across site links.

What DC is responsible for ensuring that changes made to object names in one domain are updated in references to these objects in other domains?

infrastructure FSMO role holder
The infrastructure FSMO role holder is the DC responsible for updating an object’s SID and distinguished name in a cross-domain object reference. The Infrastructure Master (IM) role should be held by a DC that is not a Global Catalog server(GC).

How do I check my DFS replication status?

You could use a PowerShell command line from Microsoft.

  1. Get-DfsrBacklog: This command shows retrieves pending updates between two computers that participate in DFS-R file replication service.
  2. Get-DfsrState: This command shows you the current replication state of DFS-R in regard to its DFS replication group partners.

How do you check AD replication and common replication issues?

Use either of the following methods to view replications errors:

  1. Download and run the Microsoft Support and Recovery Assistant tool OR Run AD Status Replication Tool on the DCs.
  2. Read the replication status in the repadmin /showrepl output. Repadmin is part of Remote Server Administrator Tools (RSAT).

What does AD replication do?

Active Directory replication is the method of transferring and updating Active Directory objects from one DC to another DC. The connections between DCs are built based on their locations within a forest and site.

How do you replicate an ad?


  1. Open the Active Directory Sites and Services snap-in.
  2. Browse to the NTDS Setting object for the domain controller you want to replicate to.
  3. In the right pane, right-click on the connection object to the domain controller you want to replicate from and select Replicate Now.

Which of the following is responsible for assigning a bridgehead?

CIT233 Ch 1 and 2 Advanced AD terms

Term Definition
Inter-Site Topology Generator (ISTG) A designated domain controller in each site that’s responsible for assigning bridgehead servers to handle replication for each partition.
intersite replication Active Directory replication that occurs between two or more sites.

What’s the best way to create a replication topology?

There are two methods for creating a replication topology: Use the KCC to create connection objects. This method is recommended if there are 100 or fewer sites. Use a scripted or third-party tool for the creation of connection objects. This method is recommended if there are more than 100 sites.

What kind of topology is used in DFS?

FRS is also used for DFS. Components of the replication topology such as the KCC, connection objects, site links, and site link bridges are to be checked by the administrator. There are two methods for creating a replication topology:

How does an intra-site replication topology work?

Intra-site replication topology is a bi-directional ring built using domain controller GUIDs. If a ring contains seven or more DCs, bi-directional connections are added to keep the path between any pair to less than three hops. New DCs configured in the site are included in the ring.

How does replication occur between two domain controllers?

For replication to occur between two domain controllers, the server object of one must have a connection object that represents inbound replication from the other. All replication connections for a domain controller are stored as connection objects under the NTDS Settings object.
