While we're on the subject of Windows networking stupidities, does
anybody know how to force Windows to set the correct network broadcast
address?  If you are using one of the reserved private subnets, Windows
(2000 and up, at least) ignores the actual subnet mask that you set
/when calculating the broadcast address/ and assumes that you have used
the typical netmask.  For example, if you have chosen to divide a
network into 10.x.x.x/16 subnets, it will set 10.255.255.255 as the
broadcast address on all of them.  It does this even when using DHCP, as
I discovered after explicitly adding the broadcast address to dhcpd.conf

Anybody know how to make this mad operating system behave on a network?
Finding a solution has been made more difficult by the fact that MS do
not use the term "broadcast address" anywhere in their documentation,
presumably because they do not allow you to manipulate it.
