Does DFS Replication require time synchronization between servers?
No. DFS Replication does not explicitly require time synchronization between servers. However, DFS Replication does require that the server clocks match closely. The server clocks must be set within five minutes of each other (by default) for Kerberos authentication to function properly. For example, DFS Replication uses time stamps to determine which file takes precedence in the event of a conflict. Accurate times are also important for garbage collection, schedules, and other features.
