Cisco IP helper / DHCP Issue

We have a branch (branch C) that will not pull dhcp even though we have setup the ip helper and we have it working at other branches.  Basically the DHCP server is two hops away.  We tried to setup a DHCP server 1 hop away for testing and it would not grab there either.  Any thoughts on where to start??? Since we have it working at other branches we're a bit stumped.

Thanks!

Another thing... on the remote routers there are two ip addresses bound to the Ethernet interface and the addresses.  We have an additional ip secondary bound to each of our routers ethernet ports.

Try using the "ip dhcp-server" global command with the ip helper-address command on the far remote router.

Router(config)#ip dhcp-server <ip of dhcp server>

Another thought...   Is the scope on the server for branch C correctly configured with a default gateway address of the primary IP address of the ethernet interface of the router.

No... it is set to the secondary which works at 3 other branches just not the one we are currently working on.  We are suspecting an older version of Cisco IOS.

You need to have the "ip helper-address" under all the ethernet interface configurations along the path.
Is that configured so??
Also, have you tried with the "ip dhcp-server" global command as well?

What version of the IOS is on each of the routers along the path?
