How do I change my inter topology generator?
Here’s how to do it.
- Open ADSIEDIT.msc.
- Expand Configuration [DomainController].
- Expand CN=Configuration,DC=,DC=.
- Expand CN=Sites.
- Highlight CN= for the site where you want to change the ISTG Server.
- In the details pane, right-click on CN=NTDS Site Settings and select Properties.
What is Intersite Topology Generator?
The intersite topology generator is an Active Directory process that defines the replication between sites on a network. A single domain controller in each site is automatically designated to be the intersite topology generator. It automatically selects one or more domain controllers to become bridgehead servers.
How do you find the Intersite Topology Generator?
Solution
- Open the Active Directory Sites and Services snap-in.
- Click on the site you are interested in.
- In the right pane, double-click on the NTDS Site Settings object.
- The ISTG will be displayed under Inter-Site Topology Generator if one is present.
How do I disable KCC?
Solution
- Open ADSI Edit.
- Connect to the Configuration Naming Context if it is not already displayed.
- In the left pane, browse the Configuration Naming Context → Sites.
- Click on the site you want to disable the KCC for.
- In the right pane, double-click CN=NTDS Site Settings .
- Modify the options attribute.
- Click OK.
How do you check replication topology?
How to check if domain controllers are in sync with each other?
- Step 1 – Check the replication health.
- Step 2 – Check the inbound replication requests that are queued.
- Step 3 – Check the replication status.
- Step 4 – Synchronize replication between replication partners.
- Step 5 – Force the KCC to recalculate the topology.
What is replication topology?
The Active Directory replication topology most commonly deployed in this scenario is based on a hub-and-spoke design, where branch domain controllers in multiple sites replicate with a small number of bridgehead servers in a hub site. One of the benefits of deploying RODC in this scenario is unidirectional replication.
How do I configure KCC?
Solution
- Open the Active Directory Sites and Services snap-in.
- In the left pane, browse to the NTDS Settings object for the server you want to trigger the KCC for.
- Right-click on NTDS Settings , select All Tasks, and Check Replication Topology.
- Click OK.
What is knowledge consistency KCC?
Knowledge Consistency Checker (KCC) is a Microsoft Active Directory component that automatically generates and maintains the intra-site and inter-site replication topology. Knowledge Consistency Checker creates connection objects that link Domain Controllers into a common replication topology.
How do I run KCC manually?
To force the KCC to run, perform the following steps: 1. In Active Directory Sites and Services, in the console tree, expand Sites, expand the site that contains the server on which you want to run the KCC, expand Servers, and then select the server object for the domain controller that you want to run the KCC on.
How to change the inter-site topology generator?
At 30-minute intervals, the current intersite topology generator notifies every other domain controller in the site of its existence by writing the attribute interSiteTopologyGenerator on the NTDS Settings object under its domain controller object in the configuration directory partition.
Which is domain controller holds the intersite topology generator role?
The domain controller that holds the intersite topology generator role performs two functions: ■ It automatically selects one or more domain controllers to become bridgehead servers. This way, if a bridgehead server becomes unavailable, it automatically selects another bridgehead server, if possible.
How does the intersitetopologygenerator attribute get propagated?
As the interSiteTopologyGenerator attribute gets propagated to other domain controllers by Active Directory replication, the KCC on each of these computers monitors this attribute to verify that it has been written. If a period of 60 minutes elapses without a modification, a new intersite topology generator takes over.
When to use cmdlet for Intersite replication?
Indicates whether the cmdlet prevents the Knowledge Consistency Checker (KCC) that functions as the intersite topology generator (ISTG) from generating connections for intersite replication. Use this option when you want to create manual intersite connections (disable the ISTG) but retain the KCC to generate intrasite connections.
