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 test my DC connection?
You can run “echo %logonserver%” in a command line to view the current connected DC. DC have an Active Directory Users and Computers console in Administrative Tools, Member Servers don’t. If you use the “Rename this computer or join a domain” button a DC will give a error msg, Member server will allow it.
How do you troubleshoot DC replication?
If AD DS cannot be removed normally while the server is connected to the network, use one of the following methods to resolve the problem:
- Force AD DS removal in Directory Services Restore Mode (DSRM), clean up server metadata, and then reinstall AD DS.
- Reinstall the operating system, and rebuild the domain controller.
What is the purpose of the Knowledge Consistency Checker KCC?
The Knowledge Consistency Checker (KCC) automatically checks for directory consistency throughout an Exchange site every three hours, or whenever you modify the directory, to ensure that the directory database is consistent throughout your Exchange organization.
What do domain controller do?
A domain controller is a server that responds to authentication requests and verifies users on computer networks. Domains are a hierarchical way of organizing users and computers that work together on the same network. The domain controller keeps all of that data organized and secured.
What is domain controller CMD?

- At the Command Prompt, type: nltest /dsgetdc:domainname.
What is KCC in domain controller?
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 a domain controller DC )? Explain the roles of DC?
A domain controller is a server that responds to authentication requests and verifies users on computer networks. Domains are a hierarchical way of organizing users and computers that work together on the same network. The domain controller (DC) is the box that holds the keys to the kingdom- Active Directory (AD).
What does the knowledge consistency checker do?
The Knowledge Consistency Checker (KCC) has detected that successive attempt to replicate with the following directory service failed. The local domain controller failed to retrieve the changes requested for the following directory partition.
Why is knowledge consistency checker (KCC) showing error on rodc?
The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition. Showing Error on RODC.. The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition. There is insufficient site connectivity information for the KCC to create a spanning tree replication topology.
Why is the KDC password for a domain controller stale?
The destination domain controller’s copy of the source domain controller computer account password may be stale if it’s not using itself as the KDC. Replication failures can prevent domain controllers from having a current password value for domain controllers in a given domain. Every domain controller runs the KDC service for their domain realm.
What happens when a domain controller fails to replicate a password?
Replication failures can prevent domain controllers from having a current password values for domain controllers in a given domain. Every domain controller runs the KDC service for their domain realm. For same realm transactions, a destination domain controller favors getting Kerberos tickets from itself.
