Duplicate IPs in the Forward Lookup Zone

    Every now and then, I get PCs in the Forward Lookup Zone with duplicate IPs.
    The DC has the DNS role and the DHCP role. When DHCP assigns an IP to a PC,
    I don't think it is always deleting the record of the previous PC that had
    that IP. I think DHCP is set up correctly. I have it set to "Dynamically
    update DNS A and PTR records only if requested by the DHCP clients" and
    "Discard A and PTR records when lease is deleted". Does anyone know how to
    fix this?
