fixed-address reservations not being honored

I've got a wierd problem.  I have a Windows XP host which received a 
lease for; later I decided I'd like to move it to a reserved 
address,  I've added the reservation to the dhcp.conf file 
on both of the failover nodes, but it ipconfig /renew kept getting  So, taking an extra step, I did ipconfig /release, deleted 
the lease from both nodes leases file and did an ipconfig /renew -- 
still got  Taking it even further, I excluded 
from the range and STILL, I keep getting!

Any thoughts?  Here's the relevant snips from the config files....

subnet netmask {
                pool {
                        failover peer "failover" ;
                        option routers;
                        option domain-name-servers,;
                        option domain-name;
                        option netbios-name-servers,;
                        option netbios-node-type        8;
                        option default-lease-time       691200;
                        deny dynamic bootp clients;

host ABENNETTD600 {
        hardware ethernet 00:0f:1f:c8:91:73;

and /var/log/messages shows:

Sep 28 13:42:47 dhcptest1 dhcpd: DHCPREQUEST for from 
00:0f:1f:c8:91:73 (ABENNETTD600) via eth0
Sep 28 13:42:47 dhcptest1 dhcpd: DHCPACK on to 
00:0f:1f:c8:91:73 (ABENNETTD600) via eth0
how could this be?  That pool's range doesn't include the address it's 
getting, I'm confused (of course).
