We have Windows 2008 Servers running and providing DHCP and DNS Services to the network. So far everything is working great.
The problem is, the clients which are provided with IPs from DHCP are automatically listed in DNS with their respective hostnames. Clients are listed 2-4 times with the same name but different IPs. There is always one right IP/hostname combination and 2-4 outdated one.
Is there any easy automated way to get rid of all the outdated ones? I assume there must be some way of making an expiration time in the DNS when outdated records get purged?
