The ideal solution to this case is to keep the staging area to be as equal to the data size being replicated, since this is not possible, we should increase the staging area to be as maximum as possible / affordable by comparing the size of data to be replicated and available disk space on the primary / secondary or both servers based on event log occurrence. Run "wmic /namespace:\\root\microsoftdfs path dfsrreplicatedfolderinfo get replicatedfoldername,replicationgroupname,state". This issue continues even after you verify that Active Directory (AD) replication has converged on all domain controllers. But if you make the effort, we'll show you how to move data faster over any network. To resume the replication for this volume, use the WMI method ResumeReplication of the DfsrVolumeConfig class.
