I am trying to install .NET framework 3.5 on Server 2012 through the Role Based features and it fails. I have the DVD drive connected and it still fails after I point it to the sources/sxs folder.
I tried the command
Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
Also and it failed. What am i missing?
