While I can agree with you suggestion in principal I think that this
might be overkill in our situation. We have a relatively small network
(6-8 servers, 15-20 workstations and maybe a dozen other types of
equipment). I  our case I think we can get away with a master and a
slave DNS server running on existing servers.

I had stumbled across this before but I will have a better look at it.

We are primarily a UNIX/Linux shop and I prefer not to use windows
for such services unless I absolutely must. There are services that
we require that only run on windows so we do have windows servers in
our mix.

I think I am going to have to disagree with you here. I have been
using BIND for several years. While I have spent many hours reading
docs and man pages I definitely would not classify myself as a DNS
expert. I know that I am of above average intelligence and maybe I
just have a "blind spot" when it comes to BIND (and it has been known
to happen) but I just do not find it as straight forward to learn
as you have. Then again I am getting "on in years" so that may be
a contributing factor as well.

Anyway, thank you very much for your comments and suggestions. They 
are appreciated.

Regards, Hugh
