Hi ,
You could consider to use Always On VPN Device Tunnel in such scenes.
Always On VPN Device Tunnel was designed with a specific purpose that being to provide pre-logon network connectivity to support scenarios such as logging on without cached credentials.
AOVPN Device Tunnel takes place as the machine has booted up. It does not require the user to log in first since it only requires the machine certificate to authenticate which will be used independently of which user logs in.
