Can anyone help me to resolve my DNS problem?
Here is the problem:

For some reason there is number of duplicate IP address
with diferent hostname in our DNS table. How can I clean
them and how to avoid that happen again? Thanks a lot.
 
If you go through the archive on this newsgroup, and look for scavening, you
will likely hit our discussion of this issue. If not, here's a brief
explanation:

In short, you need to enable DNS scavenging AND get your DHCP lease duration
and DNS scavenging period in sync.
You can use dnscmd to weed out the lingering records. Like this:
dnscmd yourDNSServerName /AgeAllRecords /YourDomainName @ /Tree /F

IF DHCP is registering the clients check the DNS tab of the scope properties
that Discard forward (Name to address) lookups when lease expires.
