Follow up… For whatever reason, a few file system sub-folders were no longer accessible via anyone or any account. We also could not reset permissions or take ownership. We suspected an admin inadvertently messed up the permissions of the  folders, but not positive. With the assistance of a Linux admin and the root account, we navigated the control station CLI to /nas/quota/slot_2/root_vdm_#/ and to the specific folder(s). Editing permissions here also did not work for regaining access via Windows. In the CS CLI, we could access the problem folders, so we just created a new parent folder, moved the content to it, deleted the original folder, then renamed the new folder to the original name. I am not sure if this was the best solution, but it did the trick.
On our VNX7500, we found a few NAS file system sub-folders that our Domain Administrator accounts can no longer access. We believe  this is the result of improperly trained local site support techs who manage user and folder permissions. Am I correct in thinking that I should be able to access these folders via the control station CLI and reset permissions there? I have found the folder for our NFS Exports under /nas/quota/slot_2/, but I cannot seem to locate the CIFS/SMB shared folders. I would appreciate any guidance on this procedure, or suggestions for better way to regain this access.  Thank you, Bryan
