I am having an issue where DDNS is setup but only updating A records for non windows clients, Windows clients will only get a PTR record created for some reason.
To clear some things up:
active directory integrated zone with secure updates only
credentials setup for dhcp to update dns
server object added to dnsupdateproxy group (or whatever that group is called)
DHCP is pushing the correct connection specific suffix, also tried messing with the primary suffix on the windows client
DHCP server settings for dns as follows:
Enable DNS Dynamic updates according to the following: checked
Always Dynamically update DNS records: checked
Discard A and PTR records when lease deleted: Checked
Dynamically update DNS records for DHCP clients that do not request updates: Checked
dhcp name protection: enabled
