Hotfix: Resolve Issues in mixed Windows Server 2003 and 2012R2 Domain Controller environments

The issues were documented here –

The main issue is that users could not log on to the domain and Kerberos errors (EventID 4) were logged. This could lead to issues, and frustration, especially in migration situations.

The hotfix can be obtained here –

Enabling Windows Server 2012 R2 Essentials integration with Microsoft Online Services when there are multiple domain controllers

The latest August 2014 update rollup for Windows Server 2012 R2 has addressed this issue. The integration feature previous only worked when the Essentials server was the only domain controller in the domain, which led to some difficult workarounds in migration scenarios.

The rollup can be downloaded via Windows Update or directly here –

Hyper-V and the “Windows cannot find the Microsoft software license terms” error

I was building a new Hyper-V server using Windows Server 2012 R2 and ran into this error. The scenario? You set up a new VM using the default settings, and configure the use of Dynamic RAM.

Once the VM is set up, you start this and get to the point of typing in the license key. In the case of the Datacentre edition, with Generation2 VMs, you can use the Automatic Activation Keys as detailed in the Technet article here – And the following error occurs – “We couldn’t verify the product key. Please check your installation media.”

Alternatively, you may get the following message after selecting the operating system – “Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation.”

The solution is straightforward. You need to assign at least 576MB RAM as the starting value for the VM to bypass this problem. I usually configure my virtual servers to start with a minimum of 1024MB RAM.



Step by Step Windows 2012 R2 Remote Desktop Services

Here is a link to an excellent series of blog posts on how to set up and configure Remote Desktop Services (Terminal Services) in a clear and easy manner.



We couldn’t complete the updates. Undoing changes. Error on Windows Server 2012 R2

I ran into this problem with 3 Virtual Machines. All of them were brand new installations, so it was not an issue with badly behaving applications.

The cause appeared to be the way Gen2 virtual machines worked with a particular recent update. Gen 1 virtual machines did not present this issue.

Thanks to Susan Bradley and GurliGebis on the technet forums here (, we have a workaround.

  1. Shutdown the Virtual Machine.
  2. In the VM settings, disable Secure Boot.

  3. Start the VM and install the updates.
  4. Shutdown the VM and re-enable Secure Boot again.
  5. Start up the VM.


Replication Health Mailer for Hyper-V Replica

Here is a cool script that mails Replication State, Replication Health and resource usage by virtual machines. The report is produced in a table format, emails to one or more recipients and can be scheduled as a task.

The script was written by Sangeeth on the Microsoft Virtualization Team and can be downloaded for free here –

Hyper-V Replica Troubleshooting Wiki

The Windows Virtualization Team have set up a wiki to track and assist in troubleshooting issues in Hyper-V Replica. The guide contains links and resources to common Hyper-V Replica failure scenarios.

Configuring Microsoft Azure Online Backup on Windows Server 2012 R2 Essentials

The Essentials team have blogged the step by step instructions on how to configure Microsoft Azure backup integration with an on-premises installation of Server 2012 R2 Essentials.

The blog post can be found here –

Note that there is currently an issue if you are using the Essentials role enabled on Windows Server 2012 R2 Datacenter edition in Azure (I have not verified if on-premises Datacenter edition is OK). You will receive an error, when attempting to install the Add-in – “The add-in cannot be installed because it is not compatible with WIndows Server 2012 R2 Essentials”. We hope that there will be a fix for this soon.
