Active Directory Replication

The multi-master process that synchronizes directory changes among domain controllers within and between sites.

Definition

Intra-site replication uses change notification within seconds; inter-site replication follows site link schedules and compresses data. The Knowledge Consistency Checker (KCC) builds the replication topology. repadmin diagnoses replication.

Example

repadmin /syncall /AdeP forces replication across all partitions.

Exam tip

Replication failure symptoms include inconsistent passwords or group membership on different DCs; use repadmin and dcdiag.
