- FRS is a service for replication files between servers
- DFS is a servcie to maintain shared namespaces between servers. It provides both unique name space and referral so users can have access to shared folders by using unique namespace without having to know where the resources are
- DFS is NOT responsible for replications. Synchronization between different link targets can be achieved by using FRS, manual copy(robocopy etc.) or thirdparty tools
- Sysvol folder on DCs is replicated using FRS

- In Windows 2003 R2, DFSR, DFS' own replication service replaces FRS (or any other replication service) to sync the folders/files
- FRS is not designed for replicating big files or huge amount of data
