The simplest thing might be to move the modem to the Linux box and use PPP
there; I've always found Win32 dial-on-demand stuff to be incomprehensible
and badly (if it all) documented.
diald has a large number of followers if you want to do demand dialing; I'm
also working on some patches for pppd that allow it to do packet filtering,
which is required for sane demand dialing (you can choose to stop, say, DNS
query packets bring the line up, or keeping it up <g>).

The only thing I do recall someone saying once was that Windows does a DNS
lookup on workgroup / domain names in certain circumstances. You could 
temporarily set the DNS server addresses to something on the same subnet
(doesn't have to exist), and use tcpdump to see what the Windows box is
trying to look up.
