Open the Group Policy Management Console (GPMC).
Navigate to Computer Configuration > Policies > Windows Settings > Security Settings > Wired Network (IEEE 802.3) Policies.
Ensure that the settings match those required for your network.
Navigate to Computer Configuration > Administrative Templates > System > Device Guard.
Set Turn On Virtualization Based Security to Disabled.
If you are using third-party EAP modules, you might need to manually enable them:
Open the Registry Editor.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EapHost.
Set the ThirdPartyEapDispatcherPeerConfig value to 1.
Have a nice day.
Best Regards,
Molly
