Please see For a static client, the client will communicate directly with the authoritative DNS server to update its PTR record.It will first start by performing an SOA query for the reverse lookup name for the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.I've been unsuccessful at finding a guide on how to integrate just ISC DHCP into an AD DNS environment.The configuration file is below, but what I've noted when using ISC DHCP is that non-domain joined clients will not have an A record registered for them in forward/reverse lookup zones.You just replaced a computer; the old computer is off the network and had held the DHCP IP address of 192.168.0.10.You bring the new computer online and it obtains a DHCP lease for the same IP address. However, when you try to resolve the name of the new computer, the old computer's name still comes up. Here's how we'll start the troubleshooting process: 1.When either type of client (static or DHCP client) initiates an A record update with its authoritative DNS server, it will first start by performing an SOA query for the FQDN of the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.[ -z "$" ]; then usage exit 1 fi # Exit if no computer name supplied, unless the action is 'delete' if [ "$" = "" ]; then if [ "$" = "delete" ]; then name=$(host -t PTR "$" | awk '' | awk -F '.' '') else usage exit 1; fi fi # Set PTR address ptr=$(echo $ | awk -F '.' '') ## nsupdate ## case "$" in add) _KERBEROS nsupdate -g $ Start the dhcp server and see what happens, don't forget to stop your windows clients trying to update their own records, as this will fail.
Add the following to the /etc/dhcp/file on the primary: Replace PUT_YOUR_KEY_HERE with the key you extracted from the private key created by the dnssec command Restart both servers to apply the configuration changes.
