Hi Eric,
i think also thats not a problem from our NetApp, i'm just the stupid Netapp Admin who try to help. I told him already to change to a Service Account. They use this nt authority\system to distribute software over other workstations.
They use net use as first step but when they want access the share they get a strange error message, like you can see in the screenshots. Maybe someone else tried this and can help this guy from my company.
Else i will repeat "use a service account" and will close the discussion from my side.
so far, thanks for your post.
cheers Soeren
