  Interactions of cosmic rays with the galactic interstellar medium produce
high-energy neutrinos through the decay of charged pions and kaons. We report
on a search with the AMANDA-II detector for muon neutrinos from the region of
the galactic plane below the horizon from the South Pole (33 degrees < galactic
longitude < 213 degrees). Data from 2000 to 2003 were used for the search,
representing a total of 807 days of livetime and 3329 candidate muon neutrino
events. No excess of events was observed. For a spectrum of E^{-2.7} and
Gaussian spatial distribution (sigma = 2.1 degrees) around the galactic
equator, we calculate a flux limit of 4.8 x 10^{-4} GeV^{-1} cm^{-2} s^{-1}
sr^{-1} in the energy range from 0.2 to 40 TeV.
