Here is the criteria: You get Error 0x8007003B: An unexpected network error occurred" when creating a new folder on your Windows 2012 file server from a Windows 10 machine.
Cut to the chase: it's windows search service on the file server that it is causing the problem, simply stop the service and disable it. Your users will be able to create and rename folders once again. This is an active problem, MS is aware.
