We have recently migrated to Windows 7, and users are no longer able to view 'Previous Versions' of files on network drives. The tab is actually present, but opening the tab simply reports 'No previous versions avilable.' At the same time, the remaining XP users are still able to view previous versions (as is Server 2008), and there are actually previous versions available on the same files that report none available through Win7. I can even see the previous versions of files via XP mode on a Win7 client that cannot see them through Win7.
I have checked the local group policy on a test Win7 machine, and NONE of the options in the previous versions folder are configured. I have also gone so far as to disable hiding of previous versions, just to make sure.
Any advice on how to enable this feature in Win7?
