AVD Session host health state 'Unavailable'

Hi Team, 

 

We have Azure VD and some of the VMs/session hosts have 'power state,' as running but 'Health State' is 'Unavailable'. Pls. find the screen shot attached with more details. 

Is it possible to fix it by using 'redeploy' + reapply' option? We have no data on the VM as its pooled and not dedicated. Any other solution, pls. suggest. 

 

Regards,

    Sure you can try to redeploy, but if its failing to join the domain, there is probably a reason why and the next machine will fail too. Are you joining to Entra ID or a Local AD Domain? There were be logs associated the attempt to join the domain for each join type, you should log into the machine with the local admin account and troubleshoot.

    Thank you for your input. It appears that the domain join process has encountered an issue. To address this, I recommend the following steps:

    1. Remote Desktop (RDP) to the Problematic Server:

      • Establish an RDP session to the server experiencing domain join failure.
      • Ensure you have the necessary credentials to log in remotely.

    2. Manual Domain Join:

      • Once connected via RDP, proceed with the manual domain join process:
        • Open the System Properties dialog (you can press Win + Pause/Break or right-click on This PC and select Properties).
        • Click on the Change settings button under the Computer name, domain, and workgroup settings section.
        • In the System Properties window, click the Change button.
        • Select the Domain option, enter the domain name, and provide valid domain administrator credentials.
        • Follow the prompts to complete the domain join process.
        • Restart the server if necessary.

    3. Verify Domain Membership:

      • After joining the domain, verify that the server is now part of the domain.
      • You can check this by running the following command in Command Prompt or PowerShell:
        net config workstation

    4. Host Pool Availability:

      • Once the server successfully joins the domain, it should become available in the host pool.
