Hi Jelic-AZR,
Thank you for posting in the Q&A Forums.
When you encounter an error related to a reinstalled Windows 11 machine in an Azure Virtual Desktop (AVD) environment, specifically error code 0x9735, this is typically associated with multiple underlying issues including, but not limited to, network configuration, authentication issues, configuration issues with Azure resources, or client connectivity issues. Here are some steps that can help you diagnose and resolve the issue:
Check network connectivity:
Ensure that your virtual machine (VM) has access to all network resources and ports required for Azure Virtual Desktop Services.
Check that the VM has access to the Azure Virtual Desktop Service URLs and ports (such as *.wvd.microsoft.com and *.servicebus.windows.net, etc.).
Verify the Azure Virtual Desktop resource:
Log in to the Azure portal and check the status of all resources associated with your AVD deployment (such as host pools, application groups, workspaces, etc.).
Ensure that all resources are properly configured and that no errors are reported.
Check authentication and authorization:
Ensure that your user accounts are properly configured in Azure AD and have the appropriate permissions to access AVD resources.
If you are using conditional access or MFA, make sure that these policies do not prevent users from accessing the AVD.
View the event viewer and logs:
Open the Event Viewer on the VM and check the system logs, application logs, and security logs for any detailed error messages related to error code 0x9735.
In particular, check for any errors or warnings related to Remote Desktop Services, authentication, and Azure Virtual Desktop.
Re-register the VM to Azure Virtual Desktop:
If the VM was deleted from Active Directory and Intune and Windows 11 has since been reinstalled, you may need to re-register it to Azure Virtual Desktops.
Use the PowerShell module for Azure Virtual Desktops to reconfigure the VM and add it to the appropriate host pool and application group.
