How to clean up DNS entries?

Hi,

In my W2K3 DNS, I can see lot of HOST (A) entries of same IP address
but different hostname. I guess the previous admin did something wrong
with DHCP dynamic updates.

How can I clean up my DNS so there would be only one HOST (A) entry
for each IP address. I tried to scavenge old entries, but it did not
clean them.

Just delete the ones you don't want. If they are supposed to be there they
will be dynamically re-added in most cases. Concerning static ones not
dynamically added you will just have to use common sense in what to delete
and what not to. As long as you put thought into what you are deleting and
not go overboard you will be fine.

Is there any way to backup DNS data and restore it if something wrong
happens?

Maybe, I don't know.
I'm not aware of any.
