Error while enabling IIS optional feature IIS-ASPNET and IIS-NetFxExtensibility-CodePudding

I am unable to enable the optional feature IIS-ASPNET and IIS-NetFxExtensibility. When I am running following commands on powershell to enable features

Enable-WindowsOptionalFeature -Online -FeatureName "IIS-NetFxExtensibility" -All
Enable-WindowsOptionalFeature -Online -FeatureName "IIS-ASPNET" -All

I am getting below errors

Enable-WindowsOptionalFeature : The source files could not be downloaded.
Use the "source" option to specify the location of the files that are required to restore the feature. For more

You need to make sure the machine connect to network, otherwise it cannot install successfully. Or download the new Volume Licensing media.

You can't install features in Windows Server 2012 R2

Method 1: Connect to the Internet If the server can connect to Windows Update for the feature installation, let the server make the connection.

Method 2: Use Windows Server 2012 R2 installation media If the server can't connect to Windows Update, download the new Volume Licensing media (released on December 11, 2013) and use the Install-WindowsFeature PowerShell command.
