Windows Server 2012, .NET Framework 3.5, 0x800F0906, 0x800F081F

This week i tried to install SQL Server 2012 on a freshly provided Windows Server 2012.

During the setup the error message opened that

“… computer cannot download the required files from Windows Update”

So i tried to add the .NET 3.5 Feature from Server Manager, but that even did not work out. Once again i was prompted with the above mentioned error message.

To make a long story short, if you google the buzz words from the title of this Blog post, you will see a whole bunch of other Blog posts or questions and answers on stackoverflow.com etc pp. All this stuff did not work out. At least a colleague of mine found the solution on this Blog:

http://consulting.risualblogs.com/blog/2012/07/04/enabling-net-3-5-on-server-2012-rp-source-files-not-found/

There is also another requirement to install the .NET 3.5 ServerFeatures component before .NET 3.5 can be installed. To do this you need to run the following DISM commands;


DISM.EXE /Online /Enable-Feature /FeatureName:NetFX3ServerFeatures /Source:Z:\Sources\SXS

DISM.EXE /Online /Enable-Feature /FeatureName:NetFX3 /Source:Z:\Sources\SXS

… where Z is the drive letter of the Server 2012 Media.

Sometimes it’s just that easy.
When you know it.

Now you know it too 😉

Thank’s for reading
