Windows 2016 – Hyper-V installation Issues

October 13, 2017

After installing the Hyper-V feature on a Windows 2016 Server with 1 active NIC.

I got the problem that after the installation I had no network connection anymore …

When I installed it I had remote control over the server that was standing somewhere abroad.

So I lost all connectivity Sad smile 

What went wrong and how to fix it !

When installing the Hyper-V Server Role and Feature, I selected the Network Adapter too.


This is where it went wrong… When the server restarted I did not have any network connectivity anymore.

So I had to call someone in locally to uninstall this Feature again, but again you will run into an issue… !

Ones installed one of the problems is that you can’t uninstall the Hyper-V feature anymore.

Using the Dashboard GUI anymore, it will be Grayed Out Sad smile


Therefor I started with first removing the Hyper-V Virtual Switch … But no success.

Solution Steps :

Step A :
Deleted Virtual Switch associated with Physical NIC



Step B :

You need to do this using PowerShell to run this command as Admin

Remove-WindowsFeature -Name Hyper-V

After removing the Feature I still did not have Internet Connectivity ?

Not on LAN and not on Internet ?

Step C :

After activating the second NIC, I gained back network connectivity … Smile

When comparing the 2 NICs setttings.

The one that did NOT connect had the Network Load Balancing (NBL) active.
This must have been activated when installing the Hyper-V feature ?


After deactivating the Network Load Balancing (NBL) 

Everything ran again normal…

PS :

if all of this did not work, you can try to go this way.

Deleted the Physical Adapter from Device Management and then Scanned for Hardware changes.

Physical Adapter was found, and settings were back to their original state

Windows 10 – Offline Files not Available (Where did the Online Button Go ?)

October 4, 2017

In windows 7 using the file Explorer you could a button to work back online when you have been offine.

Example after making a VPN connection to your home base, you could switch to work online for all offline files and folders.

In Windows 10 this feature seem to have disappeared ?

But not realy ….

Solution :

Once you are offline first connect back using a VPN connection to your server….

And in the File Explorer go to EASY ACCESS  next click work OFFLINE ?

This is the confusing part… even if you are working offline you need to click it again Smile


You can monitor the status bar of the file eplorer at the bottom it should change to ONLINE


the funny part is that the label of the Butto Work Offline will never change to ONLINE Confused smile

If this does not work in your case you can try to add this registry key, reboot and try again….

VMWare – Tray Dmp Files on Citrix UserProfiles

You might notice that your Citrix Server runs out of DiskCapacity over time.

After some investigation I found out that we had over 12.000 VMWareTray dmp files counting up to serveral Gb’s !!


Problem :

The process vmwaretray.exe and vmwareuser.exe resulting in ‘Access Denied’ on the operation “RegOpenKey” against the key “HKLM\Software\VMWare. Inc.\VMWare Tools”.


Solution :

Change the permissions to the VMWare key “HKLM\Software\VMWare. Inc.” by adding ‘Read Only’ access to the proper AD Group.





So far I have not seen the .dmp show up in any of the user Terminal Services profiles anymore.


Windows – Server 2012r2 cannot install .Net Framework 3 / 3.5

September 21, 2017

This error when you try to install Microsoft .Net Framework 3 or 3.5 on a server running Windows Server 20012 R2.

Using Windows Server 2012 RC from the VHD, and selecting the .NET Framework 3.5 Feature, gives error message “The source files could not be found”


This issue continues even if you manually download the application and try to install it.

Solution :

To solve this issue, you need to install the .Net 3.5 framework from the Windows 2012 R2 installation DVD. The files are located on “Source\sxs”.

Note: To improve the speed you can copy the files from the DVD to any folder on the server.

For this example, the files were copy to “C:\temp\sxs”.

Open a CMS windows as an “Administrator” and paste the following command:

C:\Windows\system32>dism.exe /online /enable-feature /featurename:NetFX3 /Source :C:\temp\sxs /LimitAccess /all

Note: Modify the /Source attribute if needed.

If the process was successful, you will see the following message
