I am running Windows 7 as client together with Server 2008 R2. Read/write access is ok and works in the respective folders, which are synchronized for off-line use. CSC folder is moved to a dedicated drive (\??\d:\CSC) Several applications including Office can not save the files with a message that the folder is not longer available or that there is no sufficient write access (Error 200932). I get it temporarily fixed following the KB 934160 procedure and formating the CSC database. However, once the files are made available off-line again, in some folders (random) the applications can not save any longer. Thanks for your thoughts. Best Jochen

Is it also possible to loose files on the server due to replication? For the time being, I turned off-line files off and make them only available manually, when needed. Not a solution, but at least a work around. I am still curious, whether this is a special fault in my environment, or whether this happens more often. Let me know. Jochen
