If you have any Unix clients (other than the DC which will have a fixed
ipaddress) then they will not be able to update their records in AD,
Windows clients can.

Well, that is how I run it, but it should work when run on another
computer, provided that the computer is in the same dns domain, it
would also have to be a Unix domain member. You will have to modify the
script, find the lines 'server 127.0.0.1' and change '127.0.0.1' to
your DC's ipaddress.
