Turtle, 1- Be sure to have specific IP address in the ip helper-address statement (i.e. 10.1.1.254). 2- Have a DHCP scope setup on the DHCP server for each network you want DHCP supported. 3- If the client station connect via switch ports be sure to enable spantree portfast (only on endstation ports - not router or switch connected ports) 4- If client fails to negotiate an address, static define IP on a station and test routing (ping the DHCP server) Good luck.
