BIND 9 doesn't remove DDNS entries from not existing WIN2000 clients

[anonimous]

hi

I've installed the linux BIND 9.2.1 DNS server for the WIN2000 area network.
All WIN2000 machines register themselves or via DHCP (reverse entries included) on the linux BIND DNS server automatically.

But I can find some DDNS Entries from WIN2000 client machines don't existing since 1 or 2 months.
These clients had fixed IP addresses !

How to solve this problem ?
I mean, if the client machine doesn't exist anymore,
BIND should delete its DDNS entry automatically.

config file:

options {

directory "/var/lib/named";

auth-nxdomain yes;
multiple-cnames no;
cleaning-interval 60;
datasize default;
stacksize default;
coresize default;
files unlimited;
#recursion yes;

forwarders { X.X.X.X; X.X.X.X; X.X.X.X; };
forward first;

listen-on port 53 { 127.0.0.1; 10.30.1.10; };
listen-on-v6 { any; };

notify no;
};

zone "." in {
type hint;
file "root.hint";
};


zone "localhost" in {
type master;
file "localhost.zone";
};

zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0.zone";
};


/Zone entry for domain xxxx.net.
zone "xxxx.net" {
type master;
file "/var/named/xxxx.net.hosts";
allow-update { 10.30.0.0/22; };
};

zone "0.30.10.in-addr.arpa" {
type master;
file "/var/named/10.30.0.rev";
allow-update { 10.30.0.0/22; };
};

zone "1.30.10.in-addr.arpa" {
type master;
file "/var/named/10.30.1.rev";
allow-update { 10.30.0.0/22; };
};

zone "2.30.10.in-addr.arpa" {
type master;
file "/var/named/10.30.2.rev";
allow-update { 10.30.0.0/22; };
};

zone "3.30.10.in-addr.arpa" {
type master;
file "/var/named/10.30.3.rev";
allow-update { 10.30.0.0/22; };
};

Why did you use Bind and not Windows, since it's a W2K network? Just curious. Good luck.
