Problem
When you try to install .NET Framework 3.5 on machines with Microsoft Windows Server 2012 or Windows 8 you may receive the following error:
Cause
When you start installing .NET Framework 3.5 from Add features, Windows will tries to connect to Windows Update to download the required information for .NET Framework. And if your machine/server had no internet connection or unable to connect with Windows update service, this issue may occur.
According to Microsoft support, in Windows 8 and Windows Server 2012 .NET Framework is a Feature on Demand, the binaries and other files associated with the feature are not included.
Solution
Steps for Windows 8
Insert the Windows 8 installation media
Open Command Prompt as an administrator, run the following command:
# Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
Where D: is drive letter for the DVD drive or for the Windows 8 installation.
Steps for Windows 2012
Insert the Windows Server 2012 installation media.
Use Windows PowerShell and run the following command:
# Install-WindowsFeature –name NET-Framework-Core –source D:\sources\sxs
Where D: is drive letter for the DVD drive or for the Windows 2012 installation.

Disconnect Users From a Remote Desktop
qwinsta
qwinsta is the command; server is a sub command calling the server; and serverIP is the IP of the server you are connecting to. An example server IP could be 17.255.10.1.
A list will display the session ID you need to create the disconnect. The ID value will be next to the "STATE" value of Active. For this article we will say that the ID number of the session is 4. This active connection is what needs to be disconnected.
# qwinsta /server serverIP
eg: qwinsta /server 172.255.10.1
eg: qwinsta /server 172.255.10.1
rwinsta
rwinsta command is essentially resetting the session, the server will now see this and disconnect the user. SessionID is the value we found in the previous step. The full command should read as follows:
# rwinsta /server serverIP sessionID
eg: rwinsta /server 172.255.10.1 4
