Here's one. Installing SQL 2012 on Server 2012 requires .Net 3.5. Using Google-Fu turns up a few known issues where a couple of specific MS updates will prevent that feature from being installed, like https://support.microsoft.com/en-us/kb/3002547 In my case I had a server that did not have those updates installed but .Net 3.5 would still fail
Specifying a local path did not help either after putting the Server 2012 DVD in the drive http://www.danielclasson.com/install-net-framework-35-server-2012/ dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess It would get to 66% then give a "The source files could not be downloaded." message The fix? Reconfigure the server to not use WSUS temporarily, as Server 2012 uses Windows Update to grab some of the files. Presto, .Net installs and so does SQL 2012.
