I'm still trying to get away from Centos 6 but I have to get some other things working first so the business keeps running. Now I'm trying to get a new IP address for a Windows 10 PC. No matter what I do, it continues to get the same old address.
The C6 DHCP server has a defined static IP address for this PC based on its MAC address. I've deleted all references to the old address in /var/lib/dhcpd/dhcpd.leases and restarted dhcpd. I've found a way to get W10 to forget its old address and send DHCPDISCOVER to C6. But the C6 server responds by offering the old address, not the defined static address. Where is it keeping this old information?
What additional change do I need to make to the C6 DHCP server to get it to forget the old address and respond properly to the discover request?
