I have a couple questions...
I want to have AD DNS running with secure updates only. I have both windows
and unix clients registering in AD DNS. However we are using serveral
different combiniations of DHCP servers. Some are unix based. Some are CISCO
routers because of VOIP implementations. I assume the windows based clients
will update their DNS records without issue. What about the unix clients,
how can I get these unix clients and/or the DHCP servers (unix based and/or
cisco router) to dynamically update secure records in AD DNS?

Any would be appreciated.

Usually, but not always. Generally it is best to let (Windows) DHCP do
the updates.

Either the computers must be domain (or trusted domain) members of the
update must be done by a (Windows) DHCP server which is a member of
the domain or can otherwise use "update credentials".

Only Windows 2003 supports update credentials (from Microsoft) but it is
THEORECTICALLY possible that a Unix DHCP could -- learn to -- do
this. I doubt there is one out there (yet) but if you find one please post
the
details.

Modify things so that (at least) all of your NON-domain DHCP clients get
their address from a DOMAIN DHCP server which can do the secure updates.

It's the right thing to do even if the Unix services must go away.
