Replication is very slow with latency or almost getting stopped and the backlog is noticeably increased from the source to the destination server. DFSR needs to wait until files get closed, else we can clear any open sessions on the server from share management, but it's not recommended as data loss may occur. When relying on DFS-R and its algorithms for mission-critical replication, this lack of visibility can be extremely frustrating for administrators tasked with keeping these critical services operational and users happy. Therefore, scenarios where the DFS Replication service is unable to over-write undesired updates occurring on the 'read-only' member server with the authoritative contents of the .
