I've been running my DNS/DHCP server since NetWare 5.0- it is now on
NetWare 6.0.

We have DHCP automatically updating DNS in it's primary zone every
it assigns an IP address.

Unfortunately, it doesn't seem to clean up after itself- if a computer

never comes back and asks for an address, its name still populates the

DNS zone list.

Is there a clean way to delete host names that no longer have an IP
address, or is this a just process of just deleting them manually?
