That will not fix it - the DHCP server will still NOT give an IP 
address to the client. The server MUST be able to associate the relay 
agent address with a subnet, which means that the relay agent address 
MUST be within a subnet that either hosts the client or is in a 
shared network with the client.

Oh bother - I'd missed the detail that the relay agent address given 
was on teh same subnet as the server.
