No, I left it going to a Windows Server VM share as I couldn't wait for a resolution. If I could I would have liked to have tested it to an older version of ONTAP running native 7.x as I've had other issues with the latest 8.1.x code and cifs, supposedly they rewrote / updated SMB protocol in 8.1.1 so I'd like to rule that out, but haven't got the luxury of time so I'd rather it go to something that just worked, and lose benefits of it being a NetApp CIFS share. If you do find an answer let me know!
No, I just needed it to work, I did get some response back from a NetApp PS guy, but it no it wasn't logged with NGS (i didn't have any time available to jump through their hoops!), but it turned out to be an issue with NetApp CIFS shares and Thinapp repositories he was thinking about. It may be a known issue and they'll tell straight away what needs doing to get it to work, I should have at least logged it really, the only issue is I don't have access to the kit anymore to do any testing they may have asked me to do. If you do open a case let me know the outcome.
The solution I am working on is not in place as yet so just gathering info at the moment. I think I will drop the partner help desk an email tomorrow to see if they can find anything out internally. I will update you if I come across anything.
