  FastEthernet0/0 is up, line protocol is up

  Internet address will be negotiated using DHCP
  
  Guide: Cisco IOS IP Configuration*Guide, Release*12.2 - Configuring DHCP - Cisco Systems
  
  any ideas why this isn't working ?
  
  thanks

  The cisco link you are using is for IOS 12.2, does that match your routers IOS version?
  
  I looked up the 12.4 guide and it states-
  

  All DHCP clients send a client identifier (DHCP option 61) in the DHCP packet. To configure manual bindings, you must enter the client-identifier DHCP pool configuration command with the appropriate hexadecimal values identifying the DHCP client.

  I've tried it on my rig and it works ok, my pool is-

  ip dhcp pool F1
     host 192.168.1.101 255.255.255.0
     client-identifier 0100.1150.6b8f.bb
     domain-name XXXXXX
     dns-server 10.20.0.220
     default-router 192.168.1.1
