Further to my blog posts involving vista (and the tweaks that can help make Vista/Windows 7 compatible with Samba) I came across a registry setting that needs to be changed to get offline files to work correctly: “Set the following registry key on the Windows Vista client to prevent files from getting pulled down to the client again right after synchronizing changes to the server (due to Linux file systems having coarser timestamp resolution than Windows): Create a DWORD value named RoundUpWriteTimeOnSync under the HKLM\Software\Microsoft\Windows\CurrentVersion\NetCache key (create the key if it does not exist) and set it to 1.” from the Storage Team at Microsoft’s Blog: http://blogs.technet.com/filecab/archive/2007/03/16/using-offline-files-with-samba-emc-servers-nas-devices.aspx
