  We consider the effects of the Faddeev-Popov determinant in the Coulomb gauge
on the confinement properties of the QCD vacuum. We show that the the
determinant is needed to regularize the otherwise divergent functional
integrals near the Gribov horizon but still enables large field configurations
to generate IR enhanced running coupling. The physical gluon propagator is
found to be strongly suppressed in the
  IR consistent with expectations from lattice gauge calculations.
