Hello,

We’re currently running BIND DNS and looking to migrate back to Windows AD. Currently, DNS in AD is set to forward to BIND server. DHCP is also running on Linux.

Should I import the zone back to DC and stop forwarding and make AD as master and change BIND to slave. Then turn on DHCP on the DC and just set new scope by pointing to both DNS? In the long run, I’m trying to get rid of BIND.

Thanks for help.

Just out of curiosity, why do you want to get rid of BIND? Its pretty solid.

In a nut shell: Stop forwarding to BIND, instead have bind forward to your Windows box. During off hours turn on DHCP on your windows box with the scope preferences. Test and then turn Linux box off.

Thanks for replying back. It’s because no one know how to maintain it. I thought about keep BIND and make it as secondary DNS server. Would this be a better choice? Or there will be more problem replicating between Windows and BIND. I don’t sure if this would be a overhead for me or not. I’m sort of newbie in BIND but find it’s very interesting to work on in the past week.

Thanks

BIND is a great DNS server. It runs on all the core Internet DNS servers. So their is nothing wrong with keeping it around. The only reason I would suggest running DNS on your windows servers is because of AD, combine that with DHCP you have instant dynamic DNS for your clients.

I would suggest bind if you want to setup an authoritative DNS server. But internal use unless you want multiple Domains its not really loggical to have it when you already have AD DNS in place and don’t want to manage multiple domains.

I’d prefer to keep one place to manage. Should I set up a forward from BIND to Windows and have it run for a night before cut over to DHCP? Then stop BIND service after go with new DHCP server?

Thanks

DHCP shouldn’t matter. Just build your new scope. Test its working and shut off the old one.

Just remember to bring any/all reservations over as well as any other configuration. Its a simple move but may be time consuming if you have a lot of reservations. You could import them as well.

One last question, should I just import the ZONE files from BIND to AD DNS first as well? Would this save the time and will be minimum error?

Thanks again!

If they are the same domain then you can make Windows the secondary and Linux the primary just to make sure everything replicates correctly.

Once done you can make the Windows the primary.

I do highly recommend you have at least 2 DNS servers on your network so should one go down you have one to fall back on. Same goes for AD. So if you only have one DC, look at building another.
