Active Directory (AD) replication is the process of copying and maintaining data across multiple domain controllers in a Windows Server environment. It ensures that all domain controllers have the same copy of the directory database, which is critical for the reliable operation of AD.
To check replication in Active Directory, you can use the “repadmin” command-line tool. The “repadmin” tool provides a variety of commands that allow you to view and manage replication status, identify and troubleshoot replication errors, and perform other replication-related tasks.
