The detection of extrasolar terrestrial planets located in the habitable regions of a star system is presently beyond our observational technologies. However, systems with multiple Jupiter-like extrasolar planets may prove to be candidates for supporting terrestrial planets provided that stable regions exist. The results of numerical integrations for the systems HD74156 and HD12661, each of which have two Jovian-type planets orbiting their parent star, demonstrates that a region exists in HD74156 where a terrestrial planet can remain in orbit on a timescale of 10\^5 years, while HD12661 cannot support additional planets. The Swinburne Supercluster running the SWIFT computer code is used for the simulation of both massless test particles and Earth-mass planets to investigate their short-term dynamical stability. These results can be used to constrain the search region within HD74156 in which habitable terrestrial planets are most likely to be found.
