When the DFSR service crashes, Distributed File System Replication (DFSR) replication is stopped, and event ID 1000 is logged in the event log. The log entry resembles the following:
If you installed May 2016 update rollup 3156418 on Windows Server 2012 R2, the DFSRS.exe process may consume a high percentage of CPU processing power (up to 100 percent). This may cause the DFSR service to become unresponsive to the point at which the service cannot be stopped. When this problem occurs, you must hard-boot affected computers to restart them.
