Duplicate entries in DNS server windows 2003

Hello everyone, Im seeing duplicate entries in my DNS server, (same ip for 2 computers).
Here is the setup, please tell me if more information is needed.

Server1 (windwos 2003 SP1)
Primary Domain Controller
Primary DNS Server
DHCP

Server2 (windows 2003 SP2)
Seconary Domain Controller
Secondary DNS Server
DHCP (Disabled for the moment)

my DHCP scope range is 10.0.0.1 to 10.0.0.254
reserved 10.0.0.1 to 10.0.0.15 for servers
the lease time was 8 hours for ip address, i expanded it to 2 days. Still have duplicate entries in DNS server.

Can you please help me diagnose the problem?
Thank you
Jose.

thank you, All of the above were already selected. In the scavegging option I increased the scavvengin frequency to 1 hour. Let's see what this will do.
Thanks.

Scavenging frequency is still bound by the Aging Intervals. Nothing will be scavenged until a full Refresh has passed if you just enabled it.

Just watch out for Refresh Intervals lower than 24 hours. They can make a real mess of your domain because clients with static IP addresses (your servers and such) only refresh once every 24 hours.
