Retrieving all Hybrid AAD joined Devices

When starting a pilot for Hybrid Azure AD join, it can be useful to keep track of the number of devices that currently are already Hybrid Azure AD joined.

The most straight-forward way to do so is within the GUI of the Azure AD portal:

However, when used for reporting or other reasons, a scripted solution often is a better fit. The below PowerShell snippet returns all devices that are:

  • Known in Azure AD
  • Joined in a local domain
  • Running Windows 10

A requirement to run this script is being connected to Azure AD by using Connect-AzureAD for instance.

Get-AzureADDevice -All $true |Where-Object {($_.DeviceTrustType -eq "ServerAD") -and ($_.DeviceOSType -eq "Windows") -and ($_.DeviceOSVersion -like "10*")}


Run AAD Connect Sync & Monitor Status

Depending on the size of an AD environment (and more specifically, the number and location of objects that are in scope to be synced), a delta sync can take anywhere between a couple of seconds and significantly longer.

Checking if a sync currently is running is possible using a couple of methods. When sticking to PowerShell, the following commands can be utilized:

Start-AdSyncSyncCycle: running this command interactively when a sync is running will result in an “in your face” error message similar to the following:

Get-AdSyncScheduler: this command outputs the configuration settings of the sync process and also includes the state, wether or not it is running:

While all of the above are usable, they are not that user friendly, and require a user to retry the command in order to know *when* sync has been completed.

The below PowerShell code (let’s not call it a script, shall we?) does the following things:

  • Checks if a sync process currently is running
  • If not, starts a delta sync
  • Notifies the user / admin when the delta sync is finished
# verify if ADSync module is loaded, and if not, load it.
$module = Get-Module "ADsync"
if ($module -eq $null)
{
Import-Module AdSync
}else
{
    Write-Host "ADSync Module already loaded"
}

# verify if a sync is currently running. If not, start a delta sync
$sync = Get-AdSyncScheduler

if ($sync.SyncCycleInProgress -eq $False)
{
Start-AdSyncSyncCycle -Policytype "Delta" |Out-Null
}

# periodically test if sync is running until it's... not running anymore
do {
    Write-Host "Azure AD Connect Sync Cycle in Progress..." -ForegroundColor "Yellow"
    $sync = Get-AdSyncScheduler
    
} until ($sync.SyncCycleInProgress -eq $False)

Write-Host "Azure AD Connect Sync Cycle is finished." -ForegroundColor "Green"
