![]() The cmdlet Set-DnsClientServerAddress -InterfaceIndex 12 -ResetServerĬhanges the setting to DHCP. Multiple DNS servers are separated by commas. You can then enter the DNS servers like this: Set-DnsClientServerAddress -InterfaceIndex 12 -ServerAddresses 192.168.178.4 When configuring the IP settings, you will want to avoid using the netshĬommand-line tool from Windows Server 2008 R2 and instead use the cmdlets New-NetIPAddress If the server fails to find a WIM image, the installation wizard downloads the required files off the Internet from the Windows Update service. Option for this cmdlet lets you specify a path to a WIM image. You can use Server Manager or the PowerShell Install-WindowsFeature To install the appropriate role or feature, you will then need to access the installation media for Windows Server 2012. Option: Uninstall-WindowsFeature Server-Gui-Shell -Remove If you want to remove a role or a feature completely, use the PowerShell Uninstall-WindowsFeature If you remove any unnecessary binaries before creating an image, you can save up to a gigabyte of storage space. One benefit of this feature is the ability to roll out servers with the use of images. The process can be reversed using the installation media for Windows Server 2012 at any time. Windows Server 2012 now lets you remove unneeded binaries with the Uninstall-WindowsFeatureĬmdlet. This approach had the advantage of quick feature installation, but the binaries unnecessarily used up storage space. Until Windows Server 2008 R2, the binaries for features and server roles were also stored on the server, even if they were not installed. ![]() The following command also installs the graphical interface: Dism /online /enable-feature /featurename:ServerCore-FullServer /featurename:Server-Gui-Shell /featurename:Server-Gui-Mgmt Alternatively, you can use the PowerShell commands: Import-Module DismĮnable-WindowsOptionalFeature -online -Featurename ServerCore-FullServer,Server-Gui-Shell,Server-Gui-Mgmt You can also connect from a computer on the network using Server Manager. To install on a Core Server, you need to run: Install-WindowsFeature Server-Gui-Mgmt-Infra ![]() You must either configure an Internet connection for the server so that it can download the required data from Windows Update or specify the folder containing the Windows Server 2012 installation files. If you install a Core Server, the server lacks the binaries for installing the graphical interface. After a few minutes, the server reboots, and you have Windows Server 2012. To do this, type powershellĪt the command prompt, and then type Install-WindowsFeature Server-Gui-Shell An important innovation in Windows Server 2012 is the ability to install the graphical interface in the PowerShell later on, which means you can convert a core server into a full-fledged server with a graphical interface, and the installed services will not be affected by the change. For example, the new Show-Commandĭirective explains the use of other parameters in more detail, and with an Internet connection, you can update the help files in PowerShell using Update-Helpįor Windows Server 2012, installing as a core server is the recommended Microsoft approach and is selected by default. ![]() In this article, I introduce some of the new and interesting commandlets (cmdlets) that can make an admin’s life easier. In PowerShell 3.0, Microsoft lets admins manage, install, or adapt virtually any service on a Windows server via the shell.
