Time to check your 802.1x networks for password-based authentication:
Credential Guard is enabled on Windows 11 Enterprise and will cause issues with password-based authentication.
Microsoft has enabled Windows Credential Guard by default in the new release of Windows 11 22H2. This means that devices running Windows 11 Enterprise will have to re-enter their credentials every time they want to connect to a network that is authenticating via PEAP-MSCHAPv2.
This will apply to networks using 802.1x with RADIUS server and username/password authentication.
