Both servers in a 2 server cluster are reporting event 4412 20,000 times per day. If I sit in the conflictAndDetected folder I can observe files appearing and disappearing. Users report that their files saved by peers at the same location are overriding each other.
The configuration began with a single server, then DFS-R was set up using the 2008 R2 wizard that set up the share on the second server. DFSN was set up independently. Windows users have drives mapped using domain based namespace (\domain.com\share). Mac users are pointed directly to the new server share created by DFS-R. It is PC users indicating most of the lost files, but there has been 2 reports by Mac users about files reverting.
I've implemented DFS-R before and the event 4412 only occurred when users simultaneously opened files and made changes, or during the initial replication. Here the two servers are in sync (backlogs are empty). Why is DFS-R detecting that the file was updated on multiple servers and why are the valid conflictAndDeleted files being replaced by non-conflictAndDeleted files?
