I have found that some ISP providers require the MAC address of the router before they will hand off an IP address. So this requires you to call them and give them the MAC address of the router and to put the following line into your interface config:
interface FastEthernet0/1 (or what interface you are using)
ip address dhcp client-id FastEthernet0/1
some time if you already have DHCP configured on the interface you will need to remove the DHCP configuration and verify that the router has released the IP address. Then you can reapply the configuration.
Good Luck, Terry
