DDNS Client problem

[#1]

Hello. I am trying to properly configure DDNS in my environment.

I am using DHCP and DNS on the NIOS.

However, when the test client runs ipconfig /registerdns, I get this:

"... update 'lab.local/IN' rejected"

I can't figure out which setting is preventing the update

Can you share a little more information on your config?

Is your Infoblox system the owner/authoritative for the .local domain?
Is it configured to allow dynamic updates? from where?

is DHCP configured to send updates to that zone?
