  The Maggiore's method, which evaluates the transition frequency that appears
in the adiabatic invariant from the highly damped modes, is used to investigate
the entropy/area spectra of the Garfinkle-Horowitz-Strominger black hole
(GHS-BH). We compute the resonance modes of the GHS-BH by using the confined
scalar waves having high azimuthal quantum number. Although the area and
entropy are characterized by the GHS-BH parameters, their quantizations are
shown to be independent of those parameters. However, both spectra are equally
spaced.
