dhcp ddns nubie

[godfather55v]

We have been running a novell dns dhcp forever.  I want to get away
from that and would like to possibly go ddns, if not full ddns at least
get a way from a canned novell, or microsoft solution.  So where do i
start?  Is linux the only way to go?  Is there ports of dns,dhcp,and
bind for windows, or netware.  I'm not overly fluent in linux, or is it
simple enough to the point that i don't have to be?

thanks all!
