Authentication in login process involves verifying user credentials against Active Directory database.

• User enters username and password

• Credentials are sent to domain controller

• Domain controller checks if user exists in AD database

• If user exists, domain controller checks if password is correct

• If password is correct, domain controller sends confirmation to user's computer

• User is granted access to resources based on their permissions in AD

KCC stands for Knowledge Consistency Checker and is used in Active Directory to ensure replication consistency.

• KCC is a built-in process in Active Directory that runs on all domain controllers.

• It is responsible for creating and maintaining the replication topology.

• KCC ensures that all domain controllers have a consistent view of the Active Directory database.

• It also creates and maintains the replication connections between domain controllers.

• KCC runs automatically and does no...read more

Replication issues can be fixed by identifying the root cause and resolving it.

• Check the replication status using tools like Repadmin and Event Viewer

• Identify the root cause such as network connectivity, DNS issues, or AD database corruption

• Resolve the issue by fixing the root cause, forcing replication, or resetting the replication topology

• Monitor the replication status to ensure the issue is resolved

DNS stands for Domain Name System. It is a hierarchical decentralized naming system for computers, services, or other resources connected to the internet or a private network.

• DNS translates domain names into IP addresses

• DNS records include A, AAAA, CNAME, MX, NS, PTR, SOA, SRV, and TXT records

• A record maps a domain name to an IPv4 address

• AAAA record maps a domain name to an IPv6 address

• CNAME record maps a domain name to another domain name

• MX record specifies the mail server r...read more

AD replication is the process of copying changes made to Active Directory objects from one domain controller to another.

• Monitor replication status using tools like Repadmin or Active Directory Sites and Services

• Check event logs for replication errors

• Ensure proper network connectivity between domain controllers

• Verify DNS settings for correct replication

• Use tools like DCDiag to diagnose and troubleshoot replication issues
