Hi, I've for quite a while been strugling with some synchronization conflicts when using Offline files. It seems a bit similar to this thread http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/c34c1870-ec5e-468e-bdcf-9b156c1d59b0 and possibly http://support.microsoft.com/kb/2002109 although I haven't noticed any tmp-files showing up on other clients. Disbling Offline Files is not an option for me. The setup is as following / To reproduce. A Windows Server 2008R2 with DFS sharing the files. A Windows 7 client is connected to the share and marks it as "Always available for offline use". When the Win7 client goes offline and then edits a file on the share (using the Offline cache) and then goes back online - after synching with sync center a sync conflict will show up saying that "A file was changed on this computer and on the server while this computer was offline". When trying to resolve the conflict in Sync center, the files on the server and the client seems completely identical. Same timestamp, same size - everything, but still it shows up as a conflict. I've noticed that this ONLY happens when using some of Microsoft's software to edit the file while offline. I've confirmed this with Office (Word and Excel 2010) and Visual Studio 2010. If I use Notepad or Paint no conflicts will show and everything is working. I've made 2 totally independant network setups. Different hardware all the way. Same problem in both setups. I haven't changed any GPO's relating to offline files. It's a fairly clean setup. - No Antivirus or 3rd party software is installed on neither client nor server. - I've been trying to synchronize the time on both client and server. - Formatted CSC-Cache/Offline database serveral times and even reinstalled clients. - Netword adapter drivers should be updated. One of the setups use VmWare vSphere and network drivers from vmware tools are installed. Some help would really be appreciated. Thanks

I suspect the following to be part of the problem - http://support.microsoft.com/kb/211632/ Is it eventually possible to disable that "feature"? At least for veryfying this is the cause?

We are seeing this problem as well with the use offline files along with redirection of the 'Documents' folder. In our network the conflicts are not limeted to files edited with Office. Selecting to keep the version 'On this computer' will not resolve the conflict, you must choose to keep the version on the file share, even though the files are obviously the same... Anyone have a solution?
