The surest and simplest way of eliminating version conflicts when using DFS is to add a true file locking solution - one that offers, at a minimum, real-time detection of file use and immediate remote locking, such as PeerLock. This assures that when a file is open at location A, all other versions - say local copies at various branch offices - are locked down, preventing anyone from opening and revising it. When the file closes, the file lock is immediately released and ready for synchronization.
