Impossible to update host pool

Question

Hello,
I am using a Host Pool with the 'Session Host Configuration' feature, which allows me to update my session hosts easily using a new image template (still in Preview). I have successfully performed several updates to the session hosts until now. However, after a service account password change, I updated the password in my Key Vault. Since then, I can no longer update or add machines to my pool. It fails with the errors 'DomainJoinedCheck' and 'DomainTrustCheck' Failed.

For testing purposes, I created a new entry in my Key Vault with a different service account, but it did not resolve the issue. It seems that the 'Session Host Configuration' does not recognize the new entry in the Key Vault.

Additionally, I created a new pool using the new image and the same Key Vault, and the machines were able to join the domain successfully. This confirms that the issue lies with the original pool, which does not seem to update the password.

Have you encountered this issue before? I would like to avoid recreating a pool from scratch every time I need to update the service account password."
Regards,
Axel

Hi Axel GLEIZES,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here
Based on your query,
I understand your concern while creating new pool it is working fine for original might be issue with that update credentials not recognizing I guess could you please restart you session host and also clearing cache also helps you do sign out of the account using the Disconnect-AzAccount cmdlet in PowerShell. After that, clear any stored contexts and authentication tokens with the Clear-AzContext cmdlet. If there's a specific context you need to remove, use the Remove-AzContext cmdlet with the appropriate context name. Finally, restart your session hosts to ensure they pick up the new credentials.

Also, mentioned in these blogs, some users have encountered the same issue and have shared troubleshooting steps. Please review them, as one of the inputs might help resolve your issue
