Understanding the Dual-Entity Problem in Hybrid Environments

In hybrid environments leveraging Azure AD and Intune for device management, encountering dual-entity issues is a common challenge. Typically, after a device reset and user login, some IT professionals observe two separate entities in Azure AD: an Azure AD registered device and a hybrid Azure AD joined device in a pending state. The goal, however, is to have the device fully hybrid Azure AD joined and enrolled in Intune. This setup allows seamless policy enforcement and management.

Root Causes of Dual-Entity Issues

• Timing of Enrollment Processes: An asynchronous or delayed process for Azure AD join and Intune enrollment can result in dual entries.
• Misconfigured SCP: An incorrect Service Connection Point (SCP) in the local Active Directory might cause conflicts during the hybrid Azure AD join process.
• Network Configuration and Connectivity Issues: Unstable connections between the on-premises AD, Azure AD, and Intune can cause devices to register improperly.
• Policy Conflicts: Conflicting or misconfigured device configuration policies in Intune might prompt multiple registrations.

Steps to Resolve the Dual-Entity Issue

Let's explore a systematic approach to troubleshoot and resolve these dual-entity problems, ensuring a single, correctly configured hybrid Azure AD joined device that is Intune enrolled:

• Verify the SCP Configuration- Ensure the SCP is correctly configured in your on-prem AD. Use the command below to confirm:

Get-ADObject -Filter 'ObjectClass -eq "serviceConnectionPoint"' -SearchBase "CN=Configuration,DC=YOUR_DOMAIN,DC=COM"

• Check Azure AD Connect Sync- Ensure the Azure AD Connect synchronization is healthy and working as expected. Sync any pending changes and verify run history:

Get-ADSyncScheduler

• Review Intune Enrollment Configurations- Check that device enrollment restrictions and configurations are not causing conflicts:

# Connect to MS Graph
Connect-MgGraph -Scopes "DeviceManagementServiceConfig.Read.All"

# List all enrollment restrictions
Get-IntuneEnrollmentRestrictionPolicy

• Evaluate Device Connectivity- Ensure devices have reliable connectivity to Azure AD and Intune services. Check for firewall rules or network configurations that might impede connectivity.
• Force a Re-Enrollment- Clear the existing registration and enforce a clean hybrid join using the dsregcmd utility:

dsregcmd /leave
shutdown /r /t 0

# After restart, verify the join status
dsregcmd /status

Prevention Strategies for Future

• Regular Reviews: Periodically review Azure AD and Intune policies to ensure configurations align with organizational requirements.
• Update Documentations: Ensure all IT documentation is up-to-date with the latest configurations and best practices.
• Automation: Utilize scripts and automation tools to regularly verify SCP settings and device compliance status.
• Continuous Monitoring: Leverage monitoring solutions to gain insights into the health of your Azure AD and Intune environments, proactively identifying potential issues.

Conclusion

Resolving dual-entity issues in a hybrid environment requires a methodical approach to identify and correct underlying problems. By adhering to the steps outlined, organizations can effectively manage device identities and ensure a single, unified presence in both Azure AD and Intune, mitigating risks and improving management capabilities.
