AvatarByBarbara Hernandez Stack Overflow Queries

In today’s rapidly evolving digital landscape, managing devices efficiently and securely is more critical than ever. Organizations increasingly rely on Azure Active Directory (AAD) to streamline identity and access management, especially as remote work becomes the norm. One common challenge IT professionals face is determining whether a remote machine is Azure AD joined—a key factor in ensuring seamless access, compliance, and security across distributed environments.

Understanding if a remote device is AAD joined helps administrators enforce policies, troubleshoot access issues, and maintain control over corporate resources. This insight not only supports better device management but also strengthens the overall security posture by confirming that endpoints adhere to organizational standards. As businesses expand their cloud infrastructure, knowing the status of remote machines becomes an essential part of modern IT operations.

This article will explore the significance of identifying AAD joined remote machines, the implications for IT management, and the general approaches used to verify device status from afar. Whether you’re an IT pro, system administrator, or security specialist, gaining clarity on this topic is a vital step toward optimizing your organization’s device ecosystem in the cloud era.

Checking Azure AD Join Status Remotely Using PowerShell

PowerShell is a powerful tool for managing and querying remote devices, including checking whether a machine is Azure AD (AAD) joined. To determine the AAD join status of a remote machine, you typically need administrative privileges and remote PowerShell access enabled on the target device.

One commonly used approach involves invoking commands remotely via PowerShell Remoting (WinRM). The key is to query the local device’s registry or system information that indicates Azure AD join status. Here’s an example of a command that can be run remotely:

“`powershell
Invoke-Command -ComputerName RemotePCName -ScriptBlock {
$aadJoinStatus = (Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ” -ErrorAction SilentlyContinue).AADJoinType
if ($aadJoinStatus) {
switch ($aadJoinStatus) {
0 { “Not joined to Azure AD” }
1 { “Azure AD joined” }
2 { “Azure AD registered” }
default { “Unknown status” }
}
} else {
“Azure AD join information not found”
}
}
“`

This script accesses the `CDJ` registry key where Windows stores join information. The `AADJoinType` value indicates the join state with numeric codes:

  • `0`: Not joined to Azure AD
  • `1`: Azure AD joined
  • `2`: Azure AD registered (typically for Azure AD registered devices, not fully joined)

If the registry key or value is missing, it likely means the device is not Azure AD joined.

To successfully run this command, ensure the following prerequisites:

  • PowerShell Remoting must be enabled on the remote device (`Enable-PSRemoting`).
  • The user running the script must have administrative rights on the target machine.
  • Network connectivity and firewall rules allow remote PowerShell sessions.

Using Microsoft Graph API to Verify Azure AD Join Status

For organizations leveraging Microsoft 365 and Azure AD, the Microsoft Graph API provides a robust programmatic way to query device information, including Azure AD join status. This approach is especially useful for managing large fleets of devices without relying on direct remote access.

The Microsoft Graph API exposes device objects with properties that reflect their join state. The relevant endpoint for devices is:

“`
GET https://graph.microsoft.com/v1.0/devices/{device-id}
“`

Within the returned JSON object, properties such as `deviceTrustType` and `deviceOSType` can indicate whether the device is Azure AD joined.

Key `deviceTrustType` values include:

  • `AzureADJoined`: The device is joined to Azure AD.
  • `DomainJoined`: The device is joined to an on-premises Active Directory domain.
  • `AzureADRegistered`: The device is registered with Azure AD but not joined.

To query this information, you must authenticate with appropriate permissions, typically requiring `Device.Read.All` or higher scopes. Here’s a simplified example of an API call using PowerShell and the Microsoft Graph SDK:

“`powershell
Connect-MgGraph -Scopes “Device.Read.All”
$device = Get-MgDevice -DeviceId “device-id-guid”
$device.deviceTrustType
“`

This returns the trust type of the device, indicating if it is Azure AD joined.

Key Differences Between Azure AD Joined and Registered Devices

Understanding the distinction between Azure AD joined and Azure AD registered devices is critical when interpreting join status results remotely. The join type affects device management capabilities and compliance policies.

Aspect Azure AD Joined Azure AD Registered
Device Ownership Typically corporate-owned Often personally owned or BYOD
Device Management Full device management via Intune or Group Policy Limited management, primarily user-based
Authentication Device-based authentication for sign-in User-based authentication only
Join Process Machine is joined directly to Azure AD Device is registered to user’s Azure AD identity
Use Case Corporate laptops and desktops Personal devices accessing corporate resources

This differentiation is important when interpreting remote checks, as Azure AD registered devices may not appear as “joined” in certain queries or management portals.

Alternative Methods to Check Azure AD Join Status Remotely

Besides PowerShell and Microsoft Graph API, there are other methods to determine a remote machine’s Azure AD join status:

  • Windows Management Instrumentation (WMI): Using WMI queries remotely via tools like `wbemtest` or PowerShell’s `Get-WmiObject` can provide system information but does not directly expose AAD join status.
  • Remote Registry Access: Administrators can connect to the remote registry and check the `CDJ` key path under `HKLM` to extract AAD join information, similar to the PowerShell method but via registry tools.
  • System Center Configuration Manager (SCCM) or Microsoft Endpoint Manager: These management platforms collect device compliance and enrollment data, including Azure AD join status, which can be queried centrally.
  • Azure AD Portal and Intune Console: While not a direct remote machine query, these portals provide device inventory with join types, useful for verifying device states without touching the endpoint.

Each method has its pros and cons based on environment constraints, administrative rights, and scale of management.

Considerations and Permissions for Remote Checking

Methods to Check if a Remote Machine Is Azure AD Joined

Determining whether a remote machine is Azure Active Directory (AAD) joined is a common administrative task in modern enterprise environments. Various approaches can be used depending on the access level, tools available, and environment configuration. Below are effective methods for verifying the Azure AD join status remotely.

Using PowerShell Remoting

PowerShell remoting enables running commands on remote systems with appropriate credentials and network access. The following commands help identify AAD join status:

  • Query the Registry: Azure AD join status is stored in the registry key:

    HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ

    Check the value of JoinType where:

    • 0 = Not joined
    • 1 = Azure AD joined
    • 2 = Hybrid Azure AD joined

    Example command:

    Invoke-Command -ComputerName RemotePC -ScriptBlock {
      Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ' -Name JoinType
    }
  • Using dsregcmd: The built-in tool dsregcmd provides comprehensive device registration details.
    Execute remotely:

    Invoke-Command -ComputerName RemotePC -ScriptBlock { dsregcmd /status }

    Look for the AzureAdJoined : YES field under the device state.

Leveraging Windows Management Instrumentation (WMI)

WMI can provide system information remotely. However, Azure AD join status is not directly exposed via standard WMI classes. Instead, querying registry values remotely via WMI is feasible:

Step Command Description
1 Get-WmiObject -Class StdRegProv -ComputerName RemotePC Access the registry provider remotely.
2 
$regPath = 'SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ'
$key = 1
(Get-WmiObject -Namespace root\default -Class StdRegProv -ComputerName RemotePC).GetDWORDValue($key, $regPath, 'JoinType')
 Retrieve the JoinType DWORD value remotely.

Checking via Microsoft Endpoint Manager / Intune

If the organization uses Microsoft Endpoint Manager (Intune), device compliance and join status can be queried from the management portal or via Graph API:

  • Microsoft Endpoint Manager Admin Center: Navigate to Devices > All devices, and review the Join type column, which indicates Azure AD join status.
  • Microsoft Graph API: Use Graph API to query device objects associated with users or device IDs. The device’s deviceEnrollmentType and deviceTrustType properties reveal join status.

Using Remote Desktop with Local Commands

When remote PowerShell or WMI access is unavailable but Remote Desktop Protocol (RDP) is accessible, administrators can log in and execute:

  • dsregcmd /status in an elevated command prompt or PowerShell window.
  • Check the system properties:
    • Right-click This PC > Properties
    • Look under Windows activation or Access work or school for Azure AD join information.

Summary of Key Registry Values Indicating Azure AD Join Status

Registry Path Value Name Value Type Description
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ JoinType DWORD Indicates device join type: 0=Not joined, 1=Azure AD joined, 2=Hybrid Azure AD joined
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ JoinedDomain String Domain name if device is domain joined or hybrid joined
