To create a stub zone, use essentially the same procedures as creating a primary or
secondary server, as detailed in the following steps:
Open the DNS Manager console.
1.
Expand the server you are adding the zone to and right-click Forward Lookup Zones.
2.
Select New Zone from the menu to open the New Zone Wizard.
3.
Click Next on the Welcome page and select Stub Zone on the Zone Type page.
4.
Click Next and enter the Zone Name. Click Next.
5.
Accept the default value in the Create A New File With This Name box and then click
Next.
6.
7.
On the Master DNS Servers page, enter the IP address or FQDN of a Master Server in
the zone for which you are creating a stub, click OK, and then click OK again.
To create a stub zone at the command line by using Windows PowerShell, use the
Add-DnsServerStubZone cmdlet. For example:
Add-DnsServerStubZone -Name TailspinToys.com `
-MasterServers 192.168.10.4 `
-ReplicationScope "Tree"
Conditional forwards allow you to specify a specific DNS server or servers to which you
can forward DNS requests based on the DNS domain for which the request is made. This is
useful when you have multiple internal namespaces (such as after a merger or acquisition).
By creating conditional forwards, you allow DNS requests to stay internal without having
to completely take over the DNS server role or create secondary zones. For example, if the
DNS server at 192.168.10.2, which is a DNS server for the TreyResearch.net domain, receives
a request for the address of tail-rdsh-105.tailspintoys.com, the DNS server would first look
to see whether it hosted the domain or a stub for it. Failing that, it would check its cache to
see whether it had already looked up the address. If it still didn't have the address, it would
next forward a request to the Internet, either to a configured forwarding address or to the
root DNS servers. But, if you have a conditional forwarder configured for TailspinToys.com at
192.168.10.102, it will instead send the request to the conditional forwarder.
Conditional forwarders can be maintained on an individual DNS server basis, or integrated
into Active Directory and replicated. To configure a conditional forwarder, follow these steps:
Open the DNS Manager console.
1.
Expand the server you are adding the forwarder to and right-click Conditional
Forwarders.
