Sam (and everyone else), check-out this link:

Looks like most of my answers are there.  =

Thanks,

As I understand it (and I'm no expert): in DNS terms the a slave and a
client (which are in sync) both share equal data presedence.

What I have done in the past when "moving" a master nameserver is to set th=
e
new one up as a slave to the old master. Initiate a zone transfer (to sync
the dns data), remove the old master and edit the config of the "new" slave=

to reflect it's new master status.

In my case the IP address of the "new" master was changed to mirror the old=

one, so my conventional slaves didn't have to be reconfigured - and I had n=
o
authentification mechanism or shared secrets to worry about. I didn't have
to touch my Glue records either.

In short, the zone transfer was a one-off to move the data about, and to le=
t
DNS worry about the local data formatting. To be interroperable the Win2K
and BIND data transfered must be in a commonly understood format - otherwis=
e
the internet would be "broken"!

I think you are assuming that a Zone transfer is just like an ftp of the
Zone file (tell me if I'm wrong!) - it's not, it's a "DNS Format" exchange
of information; which is vendor neutral.

Saying all that I have only ever performed this BIND to BIND. I would say,
do the Zone Xfer, force an enquiry on your Win2K nameserver (`dig
@win2kserver host.myzone.com` or Windows equiv.) and see for yourself if th=
e
data is moved over correctly. My money is on the fact that it will.

Again, please correct me if I'm talking tosh!

Thanks Sam.  Well, on a Bind slave I see that the file format is
different so I was just concerned that the doing a zone transfer
would transfer the data but not in the correct form for the W2K
DNS server to then be able to function as a master.  Now another
point is that database files with Bind are flat ascii files and
with W2K they are databases so that adds a another wrinkle - =

whether good or bad I don't know.  Mind you I do not want to =

simply have the W2K DNS server be a slave to the Bind server long-term.
I want to make the W2K DNS server the master and eliminate Bind =

DNS servers from my network.

If the Win2K server is a DNS slave to the BIND server(s) and does a Zone
transfer, then the format of the files stored locally on each machine is
irrelevent, surely? As long as the zone is transfered correctly (`dig @win2=
k
myzone.com`) the that's the job done - from the point of view of moving the=

data across?

I'm quite open to correction here. :-)

This will probably be the most unpopular question on this
list today but here goes:

Has anyone successfully migrated from Bind to Microsoft DNS server?

I just installed Windows 2000 Server and I have decided to migrate
from my all Solaris-based Bind and DHCP to Microsoft DNS for all of the =3D=

obvious "sucked into the Borg" reasons.  I'm not proud of it but I'm
going forward with the plan.  One of my tasks is to migrate all of the =3D

DNS entries and the DHCP config to the W2K DNS and DHCP servers.  Has
anyone done this successfuly.  =3D

I can imagine that with atleast 99.99% of the folsk on this least actively
using Bind and not W2K DNS most of you will laugh at this question but
on the off-chance that someone has done this I'm hoping to get a little
help.  I'm sort of looking for either a script to convert the tables from
one platform to the other or an approach - like making the W2K DNS server
a secondary to the Bind primary server in order to download the files.  But=
=3D

that last idea strikes me as good except that the files will not be in mast=
=3D
er
file format, right?  How do I transfer?  =3D

  My latest plan calls for getting DHCP up and running and then letting =3D=

W2K DDNS populate the DNS tables automagically.  But that means careful
DHCP server migration.

I am using Bind 8.2.3 if that helps.  No flames today please.  I'm not in t=
=3D
he
mood for it.
