Something similar on 2012R2
I'm getting something similar, but with 2012R2. I've got a 2012R2 VM which is not a member of a domain, and which I log in as a local admin. There are shared folders on a 2012R2 domain that the account can access by dint of there being a domain account with the same username/password as that local admin, and passthrough authentication makes it all transparent. Since applying the most recent updates and rebooting last week, the mapped drives work for about 20 hours, and then I lose them, with a "local device name is already in use" message. Attempting to map/remap to the resource then gives a "device is not authorized to log in from this station" message. I have to log out or reboot to restore the connections.
Biting the hand that feeds IT
