I have my dial-up machine configured the other way around; first it checks 
my internal DNS, and if that fails (if the domain being looked up is not 
abreau.net or doubleclick.net or one of the other banner-ad domains my 
internal DNS masks), and if my internal server can't reach the root 
nameservers (like now, when my cablemodem is disabled), then it fails over 
to my dial-up ISP's DNS servers.
