In this video from ITFreeTraining I will look at how to install DNS on Windows Server 2012.
The DNS install will be performed on a clean install of Windows Server 2012, no additional
roles or configuration has been performed. The procedure I will follow is that same regardless
of what roles have already been installed. In this case I will install DNS on Windows
Server 2012 standard edition. Any edition of Windows Server 2012 will support DNS. On
this server I have assigned a static IPv4 and IPv6 address. DNS requires at least one
static IP address to be configured before the install.
To start the install, launch server manager from the task bar and then select the option
add roles and features to start the Add roles and Features Wizard. Once I am past the welcome
screen, the next screen will ask if you want to install the role on a physical server or
a virtual machine. In this case, I will install DNS on this server so I will select the option
"Role-based or feature-based installation." On the next screen, you can choose which Windows
Server to install DNS on from the server pool. If the server is part of a domain, additional
servers can be added to the server pool meaning any of these servers can be managed from any
location. In this case I choose the current server and move on.
On the next screen, I need to choose the DNS Server role from the list. When I select the
role, a screen will appear telling me that an additional feature, DNS Server tools, is
required. Once I press add features I can press next and move on to the feature select
screen. In this case, I do not want to add any additional
features so I will press next and move on. The next screen will give you some information
about the DNS server. You can also obtain additional information by selecting the link
at the bottom "More information about DNS server". This link will take you into Windows
help. Once I move on, this screen will confirm the
actions that will be performed. Once I am ready to start the install, all I need to
do is press install. The install process took about a minute on
this computer but I have sped up the process so we do not have to wait. Once complete and
I have closed the wizard, notice that RAM usage for this server has gone up to 94%.
The minimum RAM requirement for Windows Server 2012 is 512 Megabytes but you can see how
adding just a single role can greatly increase the amount of RAM used. In order to improve
the performance of this server I will need to add additional RAM.
To perform DNS administration, I will go back to server manager. Notice that if I scroll
down, a new tile has been added for DNS. The options in this tile will allow me to perform
some basic administration of the DNS role. These include checking for errors, checking
performance and managing the DNS service. These options will however not allow you to
make changes to the data contained in DNS. If I select the DNS option on the far left,
this will give me detailed access to a lot of information and tools for DNS under the
one view. To access the DNS Manager in order to change
data stored in the DNS server, go to the tools menu and then select the option DNS. Here
you can see that I can now expand into the data contained in this server. If I right
click DNS at the top, I can select the option "Connect to DNS Server". This will allow me
to connect to any other DNS server on my network and perform administration on it.
That's it for this video for installing DNS on Windows Server 2012. Thanks for watching
