I'm using 'net ads join' to add Linux servers to an AD domain. The servers are multi-homed, with a public IP on eth1 and a non-routable private background network on eth0 (in the 172.20 space, used for netboots and installs and stuff -- no routing to the Internet on that network).
When I 'net ads join', it appears that a DDNS entry is getting created for the 172.20 interface. How can I prevent this from happening?
(FWIW, my powers at the AD level are very limited -- I can join servers and delete server records but that's about it...)
