You may need a more robust solution if you are looking for: a detailed status of the DFS-R replication process, a DFS-R health check, forced replication, or performance tuning. on 2008 R2 servers to have auto recovery enabled after a dirty shutdown. It will cause DFSR SYSVOL migration to fail. This issue continues even after you verify that Active Directory (AD) replication has converged on all domain controllers. Once you are able to retrieve DFS-R backlog counters, you will be able to verify how fast they are decreasing and estimate how long they will take to reach zero. These scenarios are logged as Sharing violations on either source or destination server (DFSR event 4302 on data destination server OR DFSR event 4304 on data source server), https://www.dell.com/support/article/in/en/indhs1/sln289362/sharing-violation-warning-messages-appear-in-dfs-r-event-logs-and-or-dfs-r-health-check?lang=en, https://support.microsoft.com/en-in/help/973836/the-dfsr-diagnostics-report-shows-sharing-violations-events-in-windows.
