What Do I Do When the PC Username on the Domain Controller for Authentication Is host/xxxx.xx?

Scenario Description:

A customer uses an AC to associate with the SMP and uses an AD domain controller as the authentication server. All PCs in the customer scenario are added to the domain controller, and PC usernames used for login are already added to the domain controller group and synchronized to the SMP server. (The domain controller group and members are already configured.)

Customer expectation: PC users log in from the Windows PC and click Wi-Fi to connect to the wireless network. The users do not need to enter the usernames or passwords, and the PCs automatically use the Windows credential for authentication.

Fault Description:

After most PCs served by the domain controller are connected to the wireless network associated with the domain controller, two errors as shown in the following figures occur. (When a PC attempts to connect to the wireless network multiple times, the user sometimes can use the username to log in successfully, for example, the username is KINGSLEY\shamundeswary.)

Solution:

In the domain controller settings, Windows users are configured to use their hostnames by default instead of their usernames to send authentication information.

In addition, run the gpupdate /force command on the CLI to update the group policy.
