Disabling DNS

[peter at vfemail.net]

I have a FreeBSD server that, among other things, used to provide DNS for a handful of domain names and a small network.  All DNS is now provided by new machines.  On the old machine, DNS starts when the machine boots, and bind continues to run lots of useless named and named-xfer processes throughout the day.  How do I turn off the DNS processes on the old machine and stop it from starting every time the machine boots?
