fixed-address reservations not being honored

Hi,
I've got a wierd problem. I have a Windows XP host which received a
lease for 10.6.65.110; later I decided I'd like to move it to a reserved
address, 10.6.65.125. I've added the reservation to the dhcp.conf file
on both of the failover nodes, but it ipconfig /renew kept getting
10.6.65.110. So, taking an extra step, I did ipconfig /release, deleted
the lease from both nodes leases file and did an ipconfig /renew --
still got 10.6.65.110. Taking it even further, I excluded 10.6.65.110
from the range and STILL, I keep getting 10.6.65.110!
Any thoughts? Here's the relevant snips from the config files....
subnet 10.6.65.0 netmask 255.255.255.0 {
authoritative;
pool {
failover peer "failover" ;
range 10.6.65.51 10.6.65.109;
range 10.6.65.111 10.6.65.254;
option routers 10.6.65.1;
option domain-name-servers 140.232.1.32,
140.232.1.33;
option domain-name clarku.edu;
option netbios-name-servers 10.1.1.10,
140.232.1.13;
option netbios-node-type 8;
option default-lease-time 691200;
deny dynamic bootp clients;
}
}
host ABENNETTD600 {
hardware ethernet 00:0f:1f:c8:91:73;
fixed-address 10.6.65.125;
};
and /var/log/messages shows:
Sep 28 13:42:47 dhcptest1 dhcpd: DHCPREQUEST for 10.6.65.110 from
00:0f:1f:c8:91:73 (ABENNETTD600) via eth0
Sep 28 13:42:47 dhcptest1 dhcpd: DHCPACK on 10.6.65.110 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).
Best,
Aaron Bennett
