  We obtained new VLT/ISAAC H-band observations for five MACHO LMC source stars
and adjacent LMC field regions. After combining our near-IR photometry with
HST/PC BVRI optical photometry, we compared the MACHO objects to the adjacent
field stars in a variety of color-magnitude and color-color diagrams. These
diagnostic diagrams were chosen to be sensitive to our hypothesis that at least
some of the MACHO lenses were foreground Galactic disk or thick disk M dwarfs.
For the five lensed objects we studied, our hypothesis could be ruled out for
main sequence lens masses >= 0.1 Mo for distances out to 4 kpc. On the other
hand, the fact that LMC-MACHO-5, an object not in our study, has been recently
found to have just such a foreground lens, highlights that the remainder of the
LMC MACHO objects should be searched for the signature of their lenses using
our photometric technique, or via near-IR spectroscopy. We also constructed
diagnostic color-color diagrams sensitive to determining reddening for the
individual MACHO source stars and found that these five objects did not show
evidence for significant additional reddening. At least these five MACHO
objects are thus also inconsistent with the LMC self-lensing hypothesis.
