  In a recent paper [1] we showed that N=1 supersymmetric QCD in the presence
of certain superpotential deformations has a rich landscape of supersymmetric
and non-supersymmetric vacua. In this paper we embed this theory in string
theory as a low energy theory of intersecting NS and D-branes. We find that in
the region of parameter space of brane configurations that can be reliably
studied using classical string theory, the vacuum structure is qualitatively
similar to that in the field theory regime. Effects that in field theory come
from one loop corrections arise in string theory as classical gravitational
effects. The brane construction provides a useful guide to the structure of
stable and metastable gauge theory vacua.
