  Baryogenesis, through the decays of heavy bosons, was considered to be one of
the major successes of the grand unified theories (GUTs). It was then realized
that the sphaleron processes erased any baryon asymmetry from the
GUT-baryogenesis at a later stage. In this paper, we discuss the idea of
resurrecting GUT-baryogenesis in a large class of SO(10) GUTs. Our analysis
shows that fast lepton number violating but baryon number conserving processes
can partially wash out the GUT-baryogenesis produced lepton and/or baryon
asymmetry associated with or without the sphaleron and/or Yukawa interactions.
