Active Directory (AD) was one of the first LDAP-based directories to adopt and implement multi-master replication model. In a multi master replication model, there is no single “Master” or writable Domain Controller in the domain. Instead, all Domain Controllers are writable except Read Only Domain Controllers (RODCs).
While the multi master replication model is extremely popular and useful, it also increases the complexity because AD objects can be created/deleted/modified on any Domain Controller (excluding RODCs). This becomes Active Directory replication complex and difficult to troubleshoot.
In this article, we will discuss how we can leverage the built-in Repadmin tool to view and troubleshoot replication issues.
