Setting up DNS Forwarders in Windows

SecureSchool

Summary

In a typical Microsoft Windows network, all the workstations look to the domain controllers for DNS.  The domain controllers have to look to their own DNS servers so that they can resolve data about the network.  If any computer has to resolve anything else that isn't hosted internally, it needs to know where to look.  This is where DNS Forwarders come in. Windows 2012 uses a different method to setup DNS forwarding than Windows 2008, which is also different from Windows 2000 and 2003. Refer to section B. Windows 2008 of this article if you are using Windows 2008 server. Refer to section C. Windows 2003/2000 of this article if you are using Windows 2003 or Windows 2000 server.

Applies To

SecureSchool, ISBossBox, LibraryDoor, Microsoft Windows Server

More Information

A. Windows 2012

A1. On your Windows Server 2012/2012 R2 server, bring up the Start Menu and click on Administrative Tools.


A2. When the Administrative Tools open, double-click the DNS console icon.


This will open the DNS Manager. 

A3. In the DNS Manager, double-click on Forwarders.


You should be taken to the Forwarders tab in the server’s Properties. 

A4. Click the Edit… button.


This will open the Edit Forwarders dialog. 

A5. Type in the IP addresses for your SecureSchool appliance.


It should look something like this when you’re done. 

A6. Click OK to close the dialog box.


After clicking OK, you’ll be taken back to the DNS server’s Properties. It should look something like the screenshot below.

A7. By default, the "Use root hints if no forwarders are available" box will be checked. Uncheck it.


A8. When you’re done, click OK.

Now that you've updated your Forwarders. You’ll need to clear the DNS cache. 

A9. Click the View menu and then Advanced. This will enable you to see the Cached Lookups section in the DNS console.


A10. Right-click on Cached Lookups in the DNS Manager and choose Clear Cache.


You’re done! Remember, if you have more than one Windows Server 2012/2012 R2 DNS server, you’ll need to perform this change on each one. You’ll also need to run an ipconfig.exe /flushdns on your clients if you want this to start using the SecureSchool appliance immediately. Otherwise, you can wait and they’ll move over on their own as items in the DNS cache expire.
