To the point of Windows reporting no internet access, MS does two things
to determine if the machine has internet access, as outlined here.

think that's still valid)
From a console, can these two machines do the http request and the dns
lookup when they tell you they're offline? Can the other machines do
these two things when the Windows machines can't or when the windows
machines report offline?
