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