what is the process for that please?
For changing clients?
For normal computers it would ordinarily mean modifying the DNS server handed out by your DHCP server. For servers it means manually changing TCP/IP configuration.

sorry Chris i meant checking if old server in active directory intergrated mode
Ahh sure :)
1. Open the DNS Console on the existing DC
2. Expand Forward Lookup Zones
3. Right click and open Properties for your zone
4. Verify that it lists "Type" as "Active Directory-Integrated" on the General tab

ok thanks
Zone consist of these
domainname.com.au = primary
domainname.internal = active directory integrated
domainname.com = active directory integrated
Now i have dns running on new server it has replicate all bar the primary zone from the old server. Any idea why this would be? I didnt set up the old server so not sure why primary..any thoughts?

The Primary (without AD integration) won't automatically appear because there's no automatic replication method for standard Primary zones. You have a few choices on how we deal with it.
1. Convert it to AD Integrated
Or
2. Configure a Secondary Zone (Forward Lookup Zones / New) on the new DC
Before we choose which we need to know why the zone is there. Is it your public domain name? And if it is, does that version provide answers for clients on the internet?
Chris
ASKER
yes its public and provides internet answers
Okay, then you must use the Secondary zone. On the current DC:
1. Open the DNS Console
2. Expand Forward Lookup Zone
3. Select domainname.com.au and open Properties
4. Select Zone Transfers
5. Permit Zone Transfers to the new DC (private / internal IP)
6. Optionally configure Notify, again to the IP of the new DC (private / internal IP)
Then on the new DC:
1. Open the DNS Console
2. Select Forward Lookup Zones
3. Create a new Zone. Type is Secondary
4. Name is domainame.com.au
5. Master is the internal / private IP of the first DC
6. Once the zone creation wizard completes verify that the Transfer from Master option (right click on the zone) works
Now we need to do a bit more work...
1. Correct the NS Records for domainname.com.au so that only Public IP addresses are listed
2. Ensure that the new DC can be reached from the public (it will need its own IP address)
3. You may have to update the name servers for your zone with your registrar
Note that if the new server is taking over from the old you can skip some of those steps and simply redefine the inbound NAT from your Firewall to the DNS server. You will still need to check the NS records are correct for hosting a public zone.
In this case you would open the Properties for the Secondary zone, select Change next to Type, then make the zone Primary (not AD Integrated).

ok done - the option to transfer from master does that mean i can take control and transfer to new machine by choosing this? As i will be dcpromo the old machine out of the domain when all my changes done.

Chris sorry should have asked
Can i go to old server and change that to secondary and then go to new server and change to primary?

You'd have to delete the primary zone first, don't do that until you have another primary up and running.
Once it's deleted you can safely add it back as a Secondary zone. Remember to enable Zone Transfers on the new primary (new DC).

Hey,
The first step is to check that the zone is currently set to Active Directory Integrated. If it is, the steps are simply these:
1. Install the DNS Service on the new DC
2. Wait
As the zone replicates with AD it should pop up on the new DC very soon after the DNS service is installed (if not immediately).
Once the service is up and running clients and servers will have to be encouraged to refer to it.
