An exact expression derived in the literature for the rate of dragging of inertial frames (Lense-Thirring (LT) precession) in a general stationary spacetime, is reviewed. This formula is valid beyond the weak field approximation. When used for the Kerr metric, it leads to the LT precession frequency in the {\it strong gravity} regime appropriate to compact gravitating objects like rotating neutron stars and black holes. Numerical values of the precession rate are computed for a few known cases of pulsars and compared to the precession rates in the weaker gravity regimes of the earth and the sun. We also derive the exact LT precession rates in Kerr-Taub-NUT and Taub-NUT spacetime to show that in the case of spherically symmetric, zero angular momentum NUT spacetimes, the frame-dragging effect {\it does not} vanish.
