Enable .Net 3.5 feature on Windows Server 2012

Trying to enable .Net 3.5 features from Add/Remove Roles and Features Wizard on Windows Server 2012 without Internet access may failed, as it will not be able to find the valid source. To enable .Net 3.5 in this case from the Command Prompt or PowerShell command shell with Administrative privilage, run the following command:

dism.exe /online /enable-feature /all /featurename:NetFX3 /Source:X:\Sources\SXS /LimitAccess

Replace X: with your CD\DVD Drive drive letter if the ISO is mounted or enter the correct location if you have the ISO copied into the hard drive.
