    Hi @EmilianoTriacca,

    Since the NetBIOS domain name is different from AD domain name, may I know your NetBIOS domain name is also use the number as begining?

    Reference to our user's guide, the NetBIOS domain name is the Zyxel device name for AD server to find it.

    Feel free to let me know if you not only use number as begining for your AD domain name and the NetBIOS domain name.
