I do not work with Windows so I do not know its specific but in Linux
kpathsea finds the configuration as well as other files relative to its
executable. Setting TEXMFCNF in the environment is not needed and if not
done carefully, it may be a source of problems. Could you examine
enviropnment settins of all your machines, especially diferences in TEX*

> 3) Why does TEXMFCNF reference a hard-wired (e.g.,)
> "D:/TeX/Live/2014/texmf-local/web2c" ? I have no such directory -- my
