Microsoft DNS server question
If I have a single forest with multiple domains. (Server 2008 and 2012)
Example.com is my root domain and then I still have two child domains test1.example.com and test2.example.com
My question is when I point a client pc to my root domain dns server example.com will it be able to resolve also everything in my child domains.

Yes. When you create a child domain, a delegation to the sub-domains (and DNS domain) is created in the root forest or, if DNS is configured to replicate to "All DNS servers in the Forest". In DNS you should see a delegation zone or a copy of the entire zone.
In either case, you can use the NSLOOKUP command on a client to test. From a PC, run a command prompt:
Default Server: your.DNSServer.example.com
If the DNS record returns, then you're okay to point clients to the parent. They should also work just fine if the clients point to the child domain DNS servers.
I will use a third party dns server (infoblox) as my main dns sever for all my clients.
Basically all my clients will point to third party dns server and I will replicate my root domain controller with third party dns server.
Is it okay to only replicate root domain controller to third party dns sever or must I also replicate my child cc's please advice.
You don't have to replicate the zone. Just need a stub zone with glue records for the DNS zone example.com and the rest will work fine, unless that was the reason for the Infoblox.
Each sub-domain has a different DNS zone. If you are replicating the zone only, then your will not be able to resolve sub-domains without adding stub zones ir replicating thise DNS zones as well
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
ok but when i create stub zone and do changes on it wil it replicate to my ms dns server as i any changes made on ms dns or third party dns should sync
Only if you are replicating the stub zones to the Infoblox as well. They are separate DNS zones after all. If not, you have ti manually update them.
okay thanks my last question
can I also make changes in a secondary zone and are they then update to primary zone please advice
