The best practice is to manually stop NetWorker services before rebooting. NetWorker has multiple databases so anytime a server is rebooted it is recommended that NetWorker services be stopped properly before the operating system shuts down. Improper shutdown can have unpredictable results such as database corruption, jobs stop responding, general server instability, and so forth. The most reliable way to do this is to manually stop NetWorker Services and be sure that they are stopped before rebooting.
