dhcp inform is not fetching the correct option

[S Kalyanasundaram]

Hi,
 I am running dhcp-3.0.3 with the following configuration. The windows XP client 
 comes up and gets the static IP address correctly 192.168.100.101.

After getting the IP address it sends out a dhcpinform message 
asking for option 86(nds-tree-name) but instead of replying the 
value "tree2host2" dhcp server replies from the subnet value "tree0subnet0".

Is it a bug? How to make the server to send the information from host{}

My configuration file:

ddns-update-style none;
max-lease-time 86400;
authoritative;
option broadcast-address 192.168.100.254;
option domain-name-servers 192.168.201.1;
subnet 192.168.100.0 netmask 255.255.255.0 {
default-lease-time 259200;
option domain-name "example.com";
option domain-name-servers 192.168.201.1;
option nds-tree-name "tree0subnet0";
pool {
range 192.168.100.10 192.168.100.20;
option nds-tree-name "tree1pool1";
}
host testhost {
hardware ethernet 00:14:c2:06:51:74;
default-lease-time 2147483647;
fixed-address 192.168.100.101;
option nds-tree-name "tree2host2";
}
}


Thanks,
