Hi,

I have a similar problem.

Dynamic updates are not funtioning when using "Secure Only" updates.
But when I choose "Secure and Non-Secure" it is working right away.

With "Secure and Non-Secure" I can do a "ipconfig /registerdns" on the
clients and they will get registered right away. With "Secure Only"
this approach does not work.

I am running AD integrated zones and Windows 2003 native domain and
forest. I have a dedicated DHCP user account and the DCs is member of
DNSUpdateProxy since the DHCP servers resides on the DCs.

I hope someone can help me.

The DNSUpdateProxy group cannot be used for Secure updates.
Create a new user account with a non-expiring strong password, and no
special privilegdes. On the Advnced tab of the DHCP server properties ***,
click the credentials button, enter the user name and password for the
account.

I recommend adding Windows 2000 option 002 for release IP lease on shutdown,
Always update DNS, and remove A & PTR records when lease expires.
Clear the "register this connections addresses in DNS" on the clients, and
delete all dynamic records, then run ipconfig /release & ipconfig /renew on
all clients. This causes the Account to take ownership of the records then
DHCP can keep DNS updated.
