Sounds to me like two subinterfaces/physical interfaces patched to a
switch. Is the client machine in the correct VLAN assigned to the scope
you require to use. And is the interface between the router and switch a
trunk (if subinterfaces are being used?).
i.e.
ip dhcp pool vlan2
network 172.23.100.0 255.255.25
default-router 172.23.100.254
dns-server 194.72.0.98
!
ip dhcp pool vlan3
network 172.16.1.0 255.255.255.0
default-router 172.16.1.254
option 150 ip 172.16.1.254
!
Clients in vlan2 on the switch will receive an IP address in the
172.23.100.x /24 range, whereas clients in vlan3 will get an address in
the 172.16.1.x /24 range.
The topology here is:
Router (fa0/0.2 and fa0/0.3) Physical Fa0/0 -> Switch (dot1q trunk) ->
Fa0/1
Fa0/2 switchport access vlan 2
Fa0/3 switchport access vlan 3
Hope this helps!

Do you have two DHCP scopes configured?
Please provide your configuration to help clarify the scenario.
cheers,
