Multicast setup

Ok, I'm trying to setup a dhcp server that will take the dhcp requests
from the helper-ip's from a cisco router. The dhcp server resides on one
ethernet port off of the router the helper-ips and other networks reside
on other ethernet ports of the same router. I have two subnets setup
right now, one for the dhcp pool network and one for the network
assigned to the local dhcp server network card. For some reason the dhcp
server is trying to assign IP's out of the subnet for the local
interface and getting errors that there are no free leases. The
following is the dhcp config that I am currently using, any help on this
would greatly be appreciated.

authoritative;
allow unknown-clients;
ddns-update-style ad-hoc;

# Server IP Network
subnet 172.17.101.0 netmask 255.255.255.224 {
        option routers 172.17.101.1;
        authoritative;
        # DHCP Server
        host DHCPServer {
                hardware ethernet 00:30:48:78:5b:c8;
                fixed-address 172.17.101.5;
                }
        }
