We discuss the Josephson current in superconductor/dirty normal conductor/superconductor junctions, where the superconductors have d_x2\ensuremath-y2 pairing symmetry. The low-temperature behavior of the Josephson current depends on the orientation angle between the crystalline axis and the normal of the junction interface. We show that the ensemble-averaged Josephson current vanishes when the orientation angle is \ensuremathπ/4 and the normal conductor is in the diffusive transport regime. The d_x2\ensuremath-y2-wave pairing symmetry is responsible for this fact.
