Windows 2012 WSUS No client computers have ever contacted the server Error 461

Create a WSUS GPO policy for the workstations and keep in mind that the WSUS port has changed from 80 to 8530. I wrote a tutorial how to setup a WSUS GPO.

Windows 2012 Adding of Roles and Features can’t find Installation FIles

Error Message:
Do you need to specify an alternate source path? One or more installation selections are missing source files on the destination server.

This is quite annoying and it took my also a while to figure it out the first time. In Windows 2008 you din’t need your Windows DVD anymore to add features and roles. In Windows 2012 they have changed it to save storage. This isn’t actually bad but I don’t understand why they made the installation wizard so complicated, so that you can’t figure it out on your own.

The solution to this error is somewhere at the begining of the installation. You need to choose Specify Alternate Source Path and enter your Windows 2012 dvd or load the image of it:
Specify Alternate Source Path
D:\Sources\SxS\

Windows 2012 Minimal Server Interface

If you don’t want to install the whole GUI and still have the comfort to install server features and roles easily, this might be the right option for you.

What can you use?
– Server Manager
– MMC Snap-Ins
– Subset of Control Panel

What is missing?
– Desktop
– No Windows Explorer
– No Internet Explorer etc.

To switch from GUI to Minimal Server Interface run following command in powershell:
#Install-Windowsfeature server-gui-shell –remove –restart

To switch from Core to Minimal Server Interface run following command in powershell:
#Install-Windowsfeature server-gui-shell –restart

From Windows 2012 Server Core to GUI

By default Windows 2012 Server is installed without a GUI (Graphic User Interface). But compared to Windows 2008 R2, it can be added later with following command:
#Install-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell

Unfortunately this command did not work for me because it can’t find the source. So you need to put/mount Windows 2012 Server CD first and after that run following commands:
1. Create a folder to mount Server WIM.
#mkdir C:\MountWim\
2.  Get the index number of the GUI Server image.
#dism /get-wiminfo /wimfile:d:\sources\install.wim
3. Mount the WIM for the installed Server with GUI. In my case it was DataCenter GUI which had the index number 4.
#dism /mount-wim /wimfile: d:\sources\install.wim /Index:4 /mountdir:C:\MountWim\ /readonly
4. Run powershell:
#powershell
5. Start Installation:
#Install-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell –restart –source C:\MountWim\Windows\WinSxS

Or you can mount straight away the Wim-File:
1. #Install-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell –restart –source wim:d\sources\install.wim:4

Adds found OS into Boot Manager:
bootrec /rebuildbcd
