    Hello

    Enabling RequireMsgAuth via the registry

    Open the registry editor:

    Press Win + R, type regedit, and enter.

    Navigate to the NPS configuration path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IAS\Parameters

    Create or modify the RequireMsgAuth value:

    Right-click on the right blank area and select New -> DWORD (32-bit) Value.

    Name the value RequireMsgAuth.

    Double-click the value to set the data to 1 (enabled) or 0 (disabled).

    Restart the NPS service:

    Press Win + R, type services.msc, find the Network Policy Server service, right-click and select Restart.

    Enabling limitProxyState through the registry

    Open Registry Editor:

    Press Win + R, type regedit, and enter.

    Navigate to the NPS configuration path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IAS\Parameters

    Create or modify the limitProxyState value:

    Right-click the right blank area and select New -> DWORD (32-bit) Value.

    Name the value limitProxyState.

    Double-click the value to set the data to 1 (enable) or 0 (disable).

    Restart the NPS service:

    Press Win + R, type services.msc, locate the Network Policy Server service, right-click and select Restart.

     Verify the configuration

    Check the registry values:

    Ensure that the values for RequireMsgAuth and limitProxyState are set correctly.

    Test RADIUS communications:

    Test the connection using a RADIUS client, such as a wireless access point, to ensure that the NPS is working properly.

    View the event log:

    Open the Event Viewer and navigate to: Windows Logs -> System

    Check for NPS-related errors or warnings.

    I hope the above information is helpful to you.
