Yes --- it'll check that the key you have actually works, and that the
nameserver allows DDNS updates.
The problem you describe has three components ---- it'd be good to try
testing them one at a time.
1. Is named accepting DDNS updates from the machine running DHCPD,
using the same key as DHCPD?
2. Is DHCPD generating DDNS requests for the correct zone?
3. Are clients getting the right address/name combinations?
