Join This Device to Azure Active Directory Missing

The "Join this device to Azure Active Directory" option is missing from your device's settings, and you're not sure why. This issue can occur due to a lack of permissions or incorrect configuration.

To troubleshoot, check if your Azure AD tenant is enabled for Intune. If it's not, you won't see the "Join this device to Azure Active Directory" option. You can verify this by checking your Azure AD tenant settings.

Ensure that your device meets the system requirements for Azure AD join. This includes running Windows 10 or later, and having the latest version of the Azure AD device registration service.

If your domain controllers' time is off from NTP time, it can cause issues with the Hybrid Join process. This can be fixed by ensuring your domain controllers' time is in sync with NTP time.

To troubleshoot join issues, try running the command `dsregcmd /debug /leave` to unregister the device from Azure AD. This can help resolve issues where the local device and Azure AD are not agreeing on the state of the registration.

You can also use the `dsregcmd` command with the `/join` and `/debug` parameters to display verbose output and troubleshoot the registration process. This is similar to triggering the built-in Windows Scheduled Task for Automatic-Device-Join.

Here are some additional `dsregcmd` parameters that can be helpful with troubleshooting:

You can't troubleshoot effectively without a clear plan. The key is to break down the problem into manageable chunks.

Microsoft's error code website has a simple interface that's easy to parse, making it a great resource to start with.

Creating a script that checks for error codes around the original error id is a good idea. This approach helped the author check 2143 possible error messages.

Checking a wider range of error codes can be helpful, but it's also important to filter out invalid or already resolved codes.

The author was able to get 764 unique error messages from their checks, which they saved as a JSON file.

This lookup table can then be used in a kusto query to find missing values.

You may see computers showing up in the Azure AD portal as Azure AD Registered instead of Hybrid Azure AD Joined, even after completing the process correctly.

This can happen if you didn't deploy the GPO after running the wizard in Azure AD Connect. The GPO must be applied to the endpoints, which need line of sight to DC’s for it to work properly.

Make sure the new policy has applied properly to avoid this issue.

Dsregcmd is a powerful tool for troubleshooting and managing Azure Active Directory (Azure AD) registrations. It can be used to reregister a device that has been deleted in Azure AD using the /join parameter.

You can use the /leave parameter to unregister a device from Azure AD. This can be helpful when redeploying a device or troubleshooting authentication issues.

Dsregcmd also has a /debug parameter that can be used in combination with /join and /leave to display verbose output. This can be helpful when troubleshooting issues with device registration.

Here are some useful parameters and their functions:

If you're having issues with Hybrid Azure AD Join, make sure you deployed the GPO and applied it to the endpoints. You can also use the dsregcmd /debug /leave command to resolve issues with previous registrations going stale.

Dsregcmd can also be used to troubleshoot single sign-on (SSO) issues. The SSO state output returns the current state of SSO information and configuration, and can display error messages if there are issues with the tenant ID or subscriptions.

Here are some useful commands for troubleshooting SSO issues:
