How does KCC work in Active Directory?

KCC. The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. On each domain controller, the KCC creates replication routes by creating one-way inbound connection objects that define connections from other domain controllers.

What is difference between KCC and Istg?

The KCC also uses RPC to communicate with DCs to request information when building a replication topology. The ISTG manages the intersite inbound replication connection objects for a specific site.

What is repadmin?

Repadmin is a cmd application for diagnosing AD replication issues. Via Repadmin it is easy to view replication topology for every domain controller. And use this knowledge to manually change it and initiate replication communications between controllers.

How can you tell if DCs are replicated?

To diagnose replication errors, users can run the AD status replication tool that is available on DCs or read the replication status by running repadmin /showrepl.

How often does garbage collection run on a DC?

Garbage collection is a housekeeping process that is designed to free space within the Active Directory database. This process runs on every domain controller in the enterprise with a default lifetime interval of 12 hours.

What is Ntds setting?

Every server object contains an NTDS Settings object, which represents the domain controller in the replication system. The NTDS Settings object stores connection objects, which make replication possible between two or more domain controllers.
