Long back ,I have written a post on www.windows-noob.com how to install SCCM 2007 admin console Via Software Distribution using unattended setup file(.ini). In this post,we will go through how to perform unattended installation of SCCM 2012 RC.We follow the same procedure here as we did in SCCM2007 with minor modifications
OR You can use configuration manager 2012 site server to install the console from ConfigMgrSiteServerInstallationPath>\tools\ConsoleSetup for more info read http://technet.microsoft.com/hi-in/library/gg712320(en-us).aspx#BKMK_InstallConsole
As a best practice, initiate the Configuration Manager console installation from a site server rather than the System Center 2012 Configuration Manager installation media. The site server installation method copies the Configuration Manager console installation files and the supported language packs for the site to the tools\ConsoleSetup subfolder. If you install the Configuration Manager console from the System Center 2012 Configuration Manager installation media, this installation method always installs the English version, regardless of the supported languages on the site server or the language settings for the operating system running on the computer. Optionally, you can copy the ConsoleSetup folder to an alternate location to start the installation.
To perform an unattended installation for a new System Center 2012 Configuration Manager central administration site or primary site, you can create an unattended installation script and use Setup with the /script command option. The script provides the same kind of information that the Setup Wizard prompts for except that there are no default settings. All values must be specified for the setup keys that apply to the type of installation you are using.
Step 1: open notepad file and copy the below syntax and save it as console_unattended.ini in your SMSsetup folder which you can find under ConfigMgr_2012_RC1_ENU_7678(SCCM2012 setup) folder.
Where SMSInstallDir is installation directory for SCCM 2012 Admin console
SDKServer is CAS or Primary site server .
Step 2: Open a notepad file again and copy the below syntax ,save it as as unattended.cmd in your SMSsetup folder as you did above.
REM Installing SCCM 2012RC Admin Console
%~dp0\bin\x64\setup.exe /script %~dp0\console_unattended.ini
Once you are ready,you can just double click on the unattended.cmd file if you are installing this on one or two machines else you can create a package and distribute it to collection . For screen shots how to create package and distribute it ,please refer SCCM 2007 Post available here on http://www.windows-noob.com/forums/index.php?/topic/2057-install-sccm-2007-console-via-software-distribution/ .I will see if I can post step by step guide here.
