You created a host pool and generated a registration token that expires tomorrow. Some session hosts are already registered. You plan to add more session hosts next week. What should you do so you can add the new session hosts?

Azure Virtual Desktop registration tokens are time-limited for security. Once a token expires, it cannot be extended or reused. To add new session hosts after the current token expires, you must generate a new registration token for the host pool. This new token will only be used for the new session hosts you are adding. Existing, already registered session hosts are unaffected by the expiration of the old token or the creation of a new one, as their registration is permanent once established. You cannot extend an existing token, nor is there a mechanism to automatically refresh it by restarting a service. Re-registering existing hosts is unnecessary and disruptive.
