We are looking at setting up a DFS root here at our corporate office which replicates to an off-site data-center. We will have other (remote) offices accessing the data-center and the same data via terminal server. We have figured out that this may be a problem. If somebody in corporate accesses a file on the server here, while at the same time somebody is accessing the same file on the file server in the data center, they both make changes, replication occurrs, won't somebody their work? The server has to accept one of the two versions of the file, correct? Server 2003 doesn't have any checks or balances that would help prevent from somebody losing their work, does it? Any info you can give me on a solution for this kind of scenario, and confirming my suspicians, will be greatly appreciated.
