Hard to say exactly with the information given.  My WAG is that the
user from whom you're running the cron job for is logged in and
authenticated by Windows on the second machine when cron runs but not
on the first machine.  This is assuming the share is not public, which
would mean you have a completely different (network) problem on the
first machine.
