I have no Vista clients to test with, but have you tried
"always-broadcast on;" ?
From "man dhcpd.conf" on CentOS 5.2:
always-broadcast flag;
The DHCP and BOOTP protocols both require DHCP and BOOTP clients
to set the broadcast bit in the flags field of the BOOTP
message header. Unfortunately, some DHCP and BOOTP clients do
not do this, and therefore may not receive responses from the
DHCP server. The DHCP server can be made to always broadcast
its responses to clients by setting this flag to 'on' for the
relevant scope; relevant scopes would be inside a conditional
statement, as a parameter for a class, or as a parameter for a
host declaration. To avoid creating excess broadcast traffic
on your network, we recommend that you restrict the use of this
option to as few clients as possible. For example, the
Microsoft DHCP client is known not to have this problem, as are
the OpenTransport and ISC DHCP clients.
