  In this paper we consider the information that can be obtained about a
strongly-interacting symmetry breaking sector from precision measurements of
four-fermion processes at LEP2 or a (500 GeV) NLC . Using a ``Z-peak''
subtracted approach to describe four-fermion processes, we show that
measurements of the cross section for muon production, the related
forward-backward asymmetry, and the total cross section for the production of
hadrons (except $t$'s) can place constraints on (or measure the effectsof) the
lightest vector or axial resonances present in a strong symmetry breaking
sector. We estimate that such effects will be visible at LEP2 for resonances of
masses up to approximately 350 GeV, and at a 500 GeV NLC for resonances of
masses up to approximately 800 GeV. Multiscale models, for example, predict the
presence of light vector and axial mesons in this mass range and their effects
could be probed by these measurements.
