What is KCC in Active Directory?
The Knowledge Consistency Checker (KCC) creates connection objects automatically, but they can also be created manually. Connection objects created by the KCC appear in the Active Directory Sites and Services snap-in as and are considered adequate under normal operating conditions.
What is KCC and Istg?
The KCC has two components: an intrasite KCC, which deals with replication within the site, and an Intersite Topology Generator (ISTG), which establishes connection objects between sites (only one DC in each site holds the ISTG role at any given time).
How do I disable KCC?
Solution

- 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.

- Click OK.
What is the Knowledge Consistency Checker?
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.

Knowledge Consistency Checker is present on every Domain Controller and automatically generates the “most efficient” replication topology at a default interval of every 15 minutes. Knowledge Consistency Checker creates connection objects that link Domain Controllers into a common replication topology.

How often does the KCC run?
every 15 minute
The KCC is a built-in process that runs on all DCs and helps in creating replication topology. It runs every 15 minute by default and delegates the replication path between DCs based on the connection available. The KCC automatically creates replication connections between DCs within the site.
