double entries at reverse zone by BIND 9


hi

I'm using DNS Server BIND 9.2.2 on linux SuSE 8.2 as an internal DNS server with DDNS for ca. 200 WIN2000 clients.
DDNS is working. WIN2000 DHCP Server 10.41.1.150 register all WIN2000 clients by DNS as forward and reverse, but some IP have 2 entries in the master reverse zone, for example:

# nslookup 10.41.2.2
Server: 127.0.0.1
Address: 127.0.0.1#53

2.2.41.10.in-addr.arpa name = nzh12091.
2.2.41.10.in-addr.arpa name = WK1200.blue.net.

in the master forward zone is only one entry !

why happens that ?

my BIND config file (named.conf):

options {
directory "/var/lib/named";
multiple-cnames no;
cleaning-interval 60;
datasize default;
stacksize default;
coresize default;
files unlimited;
# recursion yes;

listen-on port 53 { 10.41.1.10; };

listen-on-v6 { any; };

#allow-query { 127.0.0.1; };

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";
};

# You can insert further zone records for your own domains below.

zone "ns1.blue.net" {
type master;
file "/var/lib/named/ns1.blue.net.hosts";
also-notify {
192.168.0.5;
};
};

zone "blue.net" {
type master;
file "/var/lib/named/blue.net.hosts";
allow-update {
10.41.0.0/22;
192.168.0.0/24;
127.0.0.1;
};
also-notify {
192.168.0.5;
};
};

zone "0.41.10.in-addr.arpa" {
type master;
file "/var/lib/named/10.41.0.rev";
allow-update {
10.41.0.0/22;
127.0.0.1;
};
also-notify {
192.168.0.5;
};
};

zone "1.41.10.in-addr.arpa" {
type master;
file "/var/lib/named/10.41.1.rev";
allow-update {
10.41.0.0/22;
127.0.0.1;
};
also-notify {
192.168.0.5;
};
};

zone "2.41.10.in-addr.arpa" {
type master;
file "/var/lib/named/10.41.2.rev";
allow-update {
10.41.1.150;
127.0.0.1;
};
also-notify {
192.168.0.5;
};
};

zone "3.41.10.in-addr.arpa" {
type master;
file "/var/lib/named/10.41.3.rev";
allow-update {
10.41.0.0/22;
127.0.0.1;
};
also-notify {
192.168.0.5;
};
};
