•Setting up a Domain Name System (DNS) on Windows Server involves installing the DNS

Server Role. This tutorial will walk you through the DNS installation and configuration process

in Windows Server 2012.

•Microsoft Windows Server 2012 is a powerful server operating system capable of many

different roles and functions. However, to prevent overloading production servers with

features and options that are never used, Windows Server provides a modular approach

in which the administrator manually installs the services needed. To setup and configure

DNS, one must install the DNS Server Role on Windows Server 2012.

•Install DNS Server Role in Server 2012

•To add a new role to Windows Server 2012, you use Server Manager. Start Server Manager, click the Manage menu, and then select Add Roles and Features

•Click Next on the Add Roles and Features Wizard Before you begin window that pops up. (If you checked Skip this page by default sometime in the past, that page will, of course, not

appear.)

Now, it's time to select the installation type. For DNS servers, you will be selecting the Role-based or feature-based installation.

•At this point, you will see a pop-up window informing you that some additional tools are required to manage the DNS

Server. These tools do not necessarily have to be installed on the same server you are installing the DNS role on. If

your organization only does remote administration, you do not have to install the DNS Server Tools.

•However, in a crunch you may find yourself sitting at the server console or remotely using the console and needing

to manage the DNS Server directly. In this case, you will wish you had the tools installed locally. Unless your

company policy forbids it, it is typically prudent to install the management tools on the server where the DNS will be

housed

•Now you should see the Features window. No need to make any changes here; just click Next.

Next is an informational window about DNS Server and what it does,

although one would assume that if you've gotten this far, you are already aware of what it is. Click Next to move on.

This is the final confirmation screen before installation completes. You can check the box to Restart the destination server automatically, if you like.

Installing the DNS Server does not require a restart, but unless you've planned for the downtime, keep that box unchecked, just in case

•The DNS Server role should now be installed on your server. There should be a new DNS Role tile in your Server Manager.

•Configure DNS Server in Server 2012

•If you are an old pro with DNS server files, Windows Server 2012 does let you edit the files directly.

However, Microsoft recommends that you use the interface tools to avoid errors, especially if you are

integrating DNS with Active Directory.

•If you want to use the command line to configure your DNS, use the dnscmd command. For those of us who

don't memorize TechNet for fun, a few clicks is all it takes.

Within Server Manager, to configure the DNS Server,

click the Tools menu and select DNS. This brings up the DNS Manager window.

•We need to configure how the DNS server will work before adding any actual records. Select the DNS server to manage, then click the Action

menu, and select Configure a DNS Server. This brings up the Configure a DNS Server wizard

•Up next is the option to configure forwarders. If your DNS server ever gets a query for which it has no record, it can forward that request on to

another DNS server to see if it has the answer

•For example, in order to provide name resolution for internet connectivity, you can input your ISP name

servers here, or use a DNS provider such as OpenDNS. You can (and should) have more than one server listed in case a DNS server is unreachable for

some reason. The order forwarders are listed in is the order they are tried, so place your faster and

most reliable forwarder at the top of the list.

Click Next and your DNS server is now configured and ready for use.
