TOTD: Non-administrators access in Hyper-V, AzMan, FAQ

What is AzMan and why should I know about it?

AzMan (azman.msc) is the Windows Authorization Manager. AzMan was the preferred method to provide granular access to the Hyper-V functions to non-administrators .

Unfortunately, it was deprecated in Windows Server 2012 and it doesn’t work in Windows Server 2012 R2.

How to use AzMan?

Enter to Hyper-V host, win+r and type AzMan.msc  -> open configuration store (C:\ProgramData\Microsoft\Windows\Hyper-V\InitialStore.xml)

Then create new scope (optionally), role and tasks definition and then assign user to this role. That’s it.


Err..What about Server 2012 R2?

You may notice AzMan.msc and InitialStore.xml are still existed in 2012 R2. But…it doesn’t really work. In Server 2012 R2 Hyper-V uses simple authorization. It’s just a group “Hyper-V Administrators”.


So , if you want to provide Full Access  to Hyper-V you simply add users/groups to this built-in group. There is no RBAC (Role-Based Access Control).100% RBAC is available only in VMM.

Protected Network|Powershell

Hi, folks!

Protected Network is turned on by default for every VMs in 2012 R2. To control this option you can use GUI and Powershell.

It’s very simple to find “switch” in GUI,


but you may be a little bit confused during searching “protected network” value in powershell.

For example,

PS C:\Windows\system32> Get-VM -VMName SC_VMMR2|Get-VMNetworkAdapter|fl *

Err..where is the value for Protected Network?Улыбка

Ok. Let’s begin from what is really protected network (PN). PN adds to Hyper-V  Cluster an ability to monitor a network health for every vNICs and moves VMs to another Hyper-V node if a network disconnection is detected. = it’s a really cluster monitoring option.

To change settings of vNICs we have to use Set-VMNetworkAdapter cmdlet:

I’m dummy and want to get some help:

Get-Help Set-VMNetworkAdapter -Detailed


 -NotMonitoredInCluster <bool>

.. it what we are looking for?

Let’s try to apply some changes.

Get-VM -VMName SC_VMMR2|Set-VMNetworkAdapter -NotMonitoredInCluster $True

Get-VM -VMName SC_VMMR2| Get-VMNetworkAdapter|fl *

ClusterMonitored         : False

Check in GUI:


And finally we found what we wanted.

Sometimes (err..I mean always) we need to really understand what this feature provides and how it works.
