PowerShell: Encapsulate 64 bit cmdlet in a 32 bit context

Found a rather old but nice tip from Neil Peterson to tackle a challenge executing Powershell 64 bit cmdlets from a 32 bit execution context (Orchestrator in his example). Just wanted to share this and add it to my own blog for enhancing my toolbox.
#living in a 32 bit universe

#starting PowerShell 'sysnative' version and thus 64 bit
#more info:

$ClusterNodes = .$env:windir\sysnative\WindowsPowerShell\v1.0\powershell.exe {

 #living in a 64 bit universe
 Get-ClusterNode -Cluster clustername

SCOM: Using [bracket] NoteProperties in PowerShell

When you query class instances, you'll see a numer of properties available. Direct or inherited from parent classes. To use or filter on these class instance properties in PowerShell, you need to use a specific syntax. You either enclose with single quotes or escape with backtick. In this example i'm using an instance of the 'Windows Server' class from one of the default SCOM management packs. This class inherits the property 'IPAddress' from the base class 'Windows Computer'. Here are the useable options for PowerShell:
# ** Where-Object / ForEach-Object clause **

{ $_.'[Microsoft.Windows.Computer].IPAddress'.Value }

# ** Select-Object **
select ``[Microsoft.Windows.Computer`].IPAddress
select *.IPAddress

SCCM: Using Cmdlets from SCCM PowerShell Module

If you want to use PowerShell with SCCM, you can do two things.
  • Load the PowerShell through the SCCM Console (left top corner: Connect via Windows PowerShell)
  • Load the PowerShell module manually
When you use the manual method, the SCCM PS drive should be loaded automatically.
import-module($Env:SMS_ADMIN_UI_PATH.Substring(0,$Env:SMS_ADMIN_UI_PATH.Length-5) + '\ConfigurationManager.psd1')

You can verify this with the command Get-PSDrive command
Get-PSDrive -PSProvider CMSite

When the CMSite PowerShell Drive is not available, you can create it yourself and connect to the SCCM site. The only parameter you need is the name of the Site Server which hosts the SMS Provider. This is usually the Primary Site Server.
How to add the CMSite PSDrive manually:
New-PSDrive -Name "SCCM" -PSProvider CMSite -Root "<SCCM_SERVER>"
cd SCCM:
Of course you can use whatever name you want.

SCOM: View Folder Path hierarchy (PowerShell)

So we're six years older and still there was a small thing that I still had not fixed. It concerned the full view folder path of a SCOM Monitoring View.

In the past I wrote numerous PowerShell scripts which involved the views. Now I finally found some time to create a function to get the folder hierarchy of a given View by it's ID (guid).
Why I never thought about solving it like this, i don't know, but it appeared to be not that hard. It's a simple recursive function.

In the future I'll update the existing scripts concerning the User Scopes and will also upload a nice script which shows a complete report about all the dependancies between Management Packs and their objects used in User Roles and Notifications. This comes in handy, when you want to phase out management packs but don't know whether there are User Roles and Notification Subscriptions involved.


  • $computerName should have a name of a valid Management Server
  • $viewId needs to have a valid guid of an existing view in your SCOM environment.
New-SCOMManagementGroupConnection -ComputerName $computerName
$mg = Get-SCOMManagementGroup

function GetFolderHierarchy($folderId,$folderpath) {

    $parentfolderid = $null
    $tmpfolder = $mg.GetMonitoringFolder($folderId)   
    $tmpfolderdisplayname = $tmpfolder.DisplayName

    if ($folderpath -eq "" -Or $folderpath -eq $null) {
        $folderpath = $tmpfolderdisplayname
    } else {
        $folderpath = $tmpfolderdisplayname + "\" + $folderpath

    $parentfolderid = $

    if ($parentfolderid -ne "" -And $parentfolderid -ne $null -And $ -ne "Microsoft.SystemCenter.Monitoring.ViewFolder.Root") {
        GetFolderHierarchy $parentfolderid $folderpath
    } else { 
        return $folderpath


function GetViewHierarchy($viewId) { 

    $tmpview = $mg.GetMonitoringView($viewId)
    $parentfolderid = $tmpview.ParentFolderIds.Guid | Select -First 1
    if($parentfolderid -ne "" -And $parentfolderid -ne $null) {
        $fullpath = GetFolderHierarchy $parentfolderid
        return $fullpath + "\" + $tmpview.DisplayName

GetViewHierarchy $viewId

SCOM: Compare MP's between Management Groups with PowerShell

A short blog post about comparing management packs between SCOM environments I know there are tools available to compare management packs, but that's no fun. Creating this compare script with PowerShell to accomplish the same didn't cost me that much time. And of course, doing it yourself with PowerShell is just more fun. So here it is.

This script gives you a gridview with the differences, as well as an CSV output file.
#Compares unsealed/sealed MP's between two management groups
#Author: Michiel Wouters
#Date: 23-03-2016

   [string]$ms1="server1", # A management server of the source environment, default value
   [string]$ms2="server2", # A management server of the target environment, default value


New-SCOMManagementGroupConnection -ComputerName $ms1
$mmgtgrpconn1 = Get-SCOMManagementGroupConnection -ComputerName $ms1

New-SCOMManagementGroupConnection -ComputerName $ms2
$mmgtgrpconn2 = Get-SCOMManagementGroupConnection -ComputerName $ms2

Set-SCOMManagementGroupConnection -Connection $mmgtgrpconn1
$mgmtgrp1mps = Get-SCOMManagementPack | ? {$_.Sealed -eq $Sealed} | Select DisplayName, Name, Version | Sort DisplayName

Set-SCOMManagementGroupConnection -Connection $mmgtgrpconn2
$mgmtgrp2mps = Get-SCOMManagementPack | ? {$_.Sealed -eq $Sealed} | Select DisplayName, Name, Version | Sort DisplayName

#set SynWindow for compare object
if($mgmtgrp2mps.Count -gt $mgmtgrp1mps.count) { 
    $SyncWindow = [math]::Ceiling($mgmtgrp2mps.Count/2)
}  else { 
    $SyncWindow = [math]::Ceiling($mgmtgrp1mps.Count/2)

$comparison = Compare-Object -ReferenceObject $mgmtgrp1mps -DifferenceObject $mgmtgrp2mps -Property DisplayName, Name, Version -SyncWindow $SyncWindow | Sort DisplayName
#output to screen
$comparison | Out-GridView
#output to csv file
$comparison | Export-CSV -Path .\SCOM_MPDiff_$(Get-Date -Format "yyyyMMdd_HHmm").csv -NoTypeInformation -Delimiter ";"

SCOM: SCOM 2016 Monitoring Wishes

I noticed on the System Center: Operations Monitoring Engineering Blog that there's a request for which monitoring workloads you would like to see in SCOM 2016.

So this is your chance:

For myself, I really would like to see more effort to let end-users do more Authoring for themselves, instead of being fully dependant on the Authoring team within organizations.

As for workloads: Enhanced user experience monitoring would be nice and also more functional monitoring workloads would be a nice addon (like querying specific data in a DB) and write that data back for performance history and reporting.

SCOM: New version available MP Author SP3

Silect just released a new version, SP3, of MP Author, a free and easy to use tool for creating SCOM management pack.
Soms welcome new features:
- Improved knowledge viewing and editing in multiple language environments
- Improved XML editing
- New feature to "Check for missing display names" (Nice one when MP's are authored by multiple users with different UI locales)
- Added ability to use base classes other than LocalApplication when creating new classes
- Additional MP elements are displayed
- Added a drop down list of $$ parameters for alert messages (less Traffic for Kevin Holman's blog ;))
- Schedule property grid made more user friendly
- Improvements to memory usage
But, the use of notepad, XML editor and Authoring Console still comes in handy. Or use the Visual Studio addins for authoring.

Hyper-V: Internet Connection Sharing (ICS) with Hyper-V Virtual Switch

I'm running Hyper-V on a new machine with Windows 8.1 Update 1 and updated with the latest patches. I'm running in to issues sharing internet access from my wireless network with my VM's. This post describes a solution which worked in my case.

Internet access for Hyper-V virtual machine

To give your VM's access to the internet through your computer there are multiple options

  1. Create an external switch and let the guest system connect to the actual network
  2. Create an internal switch and share your internet connection with that Virtual Switch

I prefer option 2 and therefore created a Virtual Switch and shared my Wifi connection with that Virtual Switch.

But for some reason the guest system did not get access to the internet, but did get a DHCP lease from the interface I shared with the Virtual Switch to which the VM was connected.

Searching through the internet only resulted either in sharing your internet with an hosted network on WiFi (adhoc) or describing setting up Internet Connection Sharing (ICS) as it was supposed to work.


The Wi-Fi Hosted Network brought my to the idea that infact the hosted network was also a way to let incoming connection route through the cabled interface of the host.

The command (elevated) to see whether your WLAN driver supports Hosted Network is:
netsh wlan show driver

So what if this command also worked to show details about the LAN interface?
Nope...that command is not supported.

But what DOES work is showing the available LAN interfaces with the command:
netsh ip show interfaces

This showed no information about LAN interfaces, but a statement about the Wired AutoConfig Service.
Aha, currently i'm not connected to a LAN. Actually I always use Wifi whenever possible.

Enable the Wired AutoConfig service through services.msc

After enabling this service, I got some results back from netsh.

WLAN/Wi-Fi ICS with Virtual Switch - another try

Now let's try that second method again to share internet access. (By the way, this also solved another issue on my Hyper-V host when  i want to create Virtual Switches in the first case.)

Follow the steps:
  1. Create an internal virtual switch through the Virtual Switch Manager (give it a descriptive name like vSwitch - Shared)
  2. Share your active internet connection with that vSwitch

  1. Add a network adapter to your VM which connect to that vSwitch
  2. Verify internet access on the guest OS. Yeeh!


What's the cause of this? I think it's maybe because the Wired AutoConfig Service is possibly triggered when using a physical interface and I use a WiFi connection. Haven't tested this yet though.

But after changing the Windows display language from Dutch to English (US) it also seems to be working. Hhmm?
Maybe this is caused by a specific configuration on my system, but if this post works for you, than I'm glad I shared this.
