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,
Dmitry
I am not clear as to whether DNS updates have ever happened on your system. However, have you made sure that the DHCP sever is allowed to update the DNS, ie is not blocked (I assume Windows DHCP/DNS services can do this).
I use a Linux based DHCP and DNS and have the DNS set to accept updates from the Windows servers and DHCP server only. All update attempts initiated by the clients are ignored.
