  Actually, this is =not= Microsoft's problem at all.  DHCP requests are broadcast, so the default 
configuration of a router is to NOT propagate them to the next subnet.  This is why there's 
supposed to be 
either a DHCP server or relay agent on each subnet.  It is possible to configure a Linux router to 
=be= the 
relay agent, of course.
