DNS server to synchronzie with Windows AD / DNS

Our Window DNS is integrated with AD. However, we want to find a free solution to add one more DNS without paying for Window server. Can Centos be configured to get the DNS record from Window ? Any solution for that ?

As a rule of thumb, how many workstations or node does a DNS be supported ?

You can use bind9 on linux to do this, but lost feaures, per example only one server could be master (aka writable zone): http://www.serverlab.ca/tutorials/linux/network-services/using-linux-bind-dns-servers-for-active-directory-domains/

Linux's DNS can work like DNS forwarder in your case, yes but the Master DNS issue remain exist

during installation of CentOS, customize it and add DNS server in it or you may also install it after installing..
Muhammad BurhanManager I.T.Commented:
or you can just install centOS then follow these steps as well

change hostname,domain name,gateways and forwarder DNS IPs which should be your Master DNS or proceed with the defaults if not required.

There is already a lot of DNS records in AD DNS. How can these  record be loaded into the master DNS records.

Muhammad BurhanManager I.T.Commented:
AD DNS is actually a master DNS, there is no need as such to put something right now..what you have to do is install centos with DNS server then configure it

In case I add Centos DNS and Window DC DNS for DHCP leasing to the workstation, can a Centos DNS be redirect workstation to Window DC for authentication ?

Muhammad BurhanManager I.T.Commented:
Centos DNS server will receive queries and forward them to the DC's DNS, DC's DNS then will responsible for followups and answering new queries.

Please share the exact need of yours. cause we are not getting the actual logic/scenario for 2nd DNS
AXISHKAuthor Commented:
We have two Window DC (with DNS) setup in the domain and we want to add another DNS to the DHCP leasing. We want to offload the current DNS loading (supporting over 1000+ devices).

Window need to pay for a license cost. Hence, are considering to add Centos DNS. My concern is

1. can Centos handle the window domain login itself or can it forward this kinds of request to the Window DC server ?
2. can Centos contains the actual DNS records currently hosted in my 2 DCs ? Hence, it can ask the query by itself.

Muhammad BurhanManager I.T.Commented:
Yes, it will work.
You have to edit centos dns config file for dynamic updates.
