Cisco 1921 Router not passing DHCP Lease ip's

We have a site with 4 - Cisco 1921 routers.  Routing is working fine but we have an issue with the DHCP leases.  The router is getting the ip's from our internal DHCP server but is not issuing them to the stations. We can see the ip's on the routers. We are running HP switches at the location.

Any thoughts?

Thanks,

-Tom

Not sure if I understand the situation.

The router is obtaining its' IP address from a DHCP server?  Is there a MAC to IP assignment for that?

Or do you mean to hosts are getting IP address from a DHCP server on the other side of the router? If so, you will need an IP helper-address assigned to the interface that the hosts connect to.

ip helper-address <ip address of DHCP server>
