We have two domain controllers running Server 2012 and we have a Datto appliance (linux OS). We created a CIFS share on the appliance and when we UNC to the device from one of our DCs it immediately crashes with a bluescreen and restarts. This happens in the exact same way on both DCs. We have a terminal server running 2012 and it can access the share fine. It appears that the server is trying to access the CIFS share using NFS, which is why the minidump shows the faulting module as nfsrdr.sys. I uploaded one of the minidumps below.
