Re: Dynamic DNS updates via DHCP server

Recently I came across with a problem in configuration of DHCP server as a
proxy for DNS updates.

I need to force all DHCP clients to use DHCP server for dynamic DNS updates.
These clients include Windows XP laptops (most of them). I configured DHCP
pool to ALWAYS make updates at DNS for its clients and disabled dynamic DNS
registration on the clients.
Nothing happened. No updates initiated by DHCP server on behalf of its
clients. No records in DHCP debug log that could point to attempts to make
updates at the DNS. No records in the DNS log that connected to DHCP server.
Looks like this service just does not work. What could be a source of this
problem?

Thanks,

A few questions:
1) How long is your lease duration set
2) How long is your no refresh/refresh period set for?
3) Is you DNS zone Active Directory Integrated and have updates set
for Secure Only? If so, do you have an identity set up in the DHCP
console for secure updates?
