Windows Server 2012 R2 does not install all of the source files for the required features by default. If the server is not connected to the Internet, you will need to insert the Windows Server 2012 R2 media and select Specify an alternate source path in order to install the required features. The source files are located in the sources\sxs directory. For example, if the Windows Server 2012 R2 media is in drive D, you would set the path to
d:\sources\sxs. > It is important that you have the latest updates from Windows Update. If you are not connected to the Internet, you will need to manually install all relevant updates as well as any prerequisites to the required updates.
When the dialog box indicates that the installation has completed, you will need to reboot the server to complete the process.
Run Windows Update again to check if there are any updates to the roles and services that were installed.
If you will be using Skype for Business Server Control Panel on this server then you must also install Silverlight. To install Silverlight, see Microsoft Silverlight.
The prerequisites can be installed by running the following PowerShell command. Note that the command looks for source files in a specific order. If you are online, the command accesses Windows Update. However, if you are offline, you need to make sure the source files are available to the command. For more information about using PowerShell to install roles and features, see Install or Uninstall Roles, Role Services, or Features and Install-WindowsFeature. Don't forget to run Windows Update again after you install prerequisites, even if you use the PowerShell command.
