Q:

Microsoft DHCP server and Unix BIND dynamic DNS

Is there any way to make Microsoft DHCP server to securely dynamically update A and PTR records in Unix Bind DNS zone?
Microsoft supports secure update using username/password authentication. Bind9 support secure update using keys. But I couldn't find the way to make Microsoft DHCP to use key as it can be done with dhcpd.

A:

No, not securely.
You might be able to have a single Microsoft DNS server and then do some kind of zone transfer between that and BIND?
These links may or may not help in that regard:

How can I get BIND and Microsoft DNS to work together well?
