Al gave you already some hints on the smb2 problems.
Running a dedicated file server IMHO is not the best setup for terminal server -
try moving your data files to the terminal server if possible.

If there are already cristallyzed processes on the file server (backup),
you might daisychain them to the terminal server machine.
