FAS3020 running OnTap 7.3.2 with SMB 2.0 enabled. When we right click on a home directory and choose the Previous Versions tab we are seeing snapshots going back two weeks which is what I expect. I can open one of these fine. When we try dragging files from one of these previous versions back to the home directory it will not work under Windows 7. It works fine under Windows XP. Any ideas?
=> This cannot be quantitatively defined by NetApp but is a Microsoft support question.
Disable Directory Caching on the Windows Client. To do this, create a new DWORD registry key named DirectoryCacheLifetime in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\Parameters and set the value to0. You might need to reboot the Windows client for the setting to take effect. Note that this might have a negative performance impact. See Microsoft Technet for further information
The issue I am seeing is Previous Versions works, SMB2 works fine, traversing into snapshots and Previous Versions works fine for the most part. Only intermittently on certain directories (this one happens to contain very many files) we get the above error message. Duplicating using Previous Versions to traverse this particular directory on a Windows XP client does not exhibit the issue. Only with Windows 7.
their current guess is, that its the security-style of the qtree which is causing this..i dont't believe.. just for the records, which security styles does your volume and/or qtree have the affected share lies on?
Bug ID 373136 Title Previous-versions tab does not list entries on Windows 7 and Windows Server 2008 R2 Duplicate of Bug Severity 3 - Serious inconvenience Bug Status Fixed Product Data ONTAP Bug Type CIFS Description When Windows 7 or Windows Server 2008 R2 clients are used to access CIFS shares offered by Data ONTAP, and if the older SMB 1.0 protocol is being used, then the Windows Explorer "Previous Versions" tab for files or folder properties may fail to list any existing previous versions.
Workaround If circumstances permit, the problem may be avoided by use of the newer SMB 2.0 protocol.
Notes Before enabling the SMB 2.0 protocol, make sure that the release of Data ONTAP in use is not susceptible to the bug 356893.

I think you misunderstood my question. The bug talks about not seeing anything in the Previous Version tab under Windows 7. I have enabled SMB 2.0 so I am seeing all of my snapshots in the Previous Versions tab. What I cannot do is open one of these snapshots and copy and item from there back to the home directory where it was deleted from
I may open a case about this. Our only work around now is to send the end user to a Windows XP machine. Over the next 2-3 years that will become increasingly difficult as we phase out XP and move towards Windows 7
