How To Specify Alternate File Location For Features On Demand In Server 2012

In Windows Server 2012 the binaries for Features on Demand e.g. the .Net Framework 3.5 are not installed as part of Windows.  When you enable this type of feature Windows will attempt to contact Windows Update to download the required files.  If you’re working on a server that’s not connected to the internet this can be problematic.  One work around is to use Group Policy to specify an ISO file as an alternate file source.

Mount the Windows Server ISO into the virtual machine

Open the local Group Policy editor by typing gpedit.msc at the Start Screen

Navigate to Computer Configuration -> Administrative Templates -> System

Open the “Specify settings for optional component installation and component repair” setting

Enable the setting and type the path to the sxs folder on your ISO file.
