2 DHCP Servers, only 1 is populated

Have 2 DHCP Servers in a multi-vlan network.
I've setup 2 DHCP servers on a flat VLAN and split up the scopes and have usually found them to work.  Some clients will go to one dhcp server to get the IP's while others will show up on the 2nd DHCP server.

I set the same configuration this time on 2 servers, splitting the scope but found 1 server servicing the dhcp request while the other is empty---services an all seem to be running but no ack on requests.    any suggestions?

Do you have the servers in their associated vlans? Meaning, do you have one server with it's half of the scope in the vlan it serves addresses to, and do you have the other server in it's vlan that it's supposed to serve address to. If you still have both in the same vlan, the vlan without a dhcp server will need to have dhcp relay configured to forward dhcp requests to the server that will be serving it.

Thanks for the input.   Turns out, I had to apply relay on the core switch.  (the relay IP was incorrect).  adjusting it to the right one fixed the issue.
