Do you have any firewalls that are supposed to load, or any networking services like VPN, etc., that are not opening?

it can actually boot? from that error message it sounds like he isn't even booting.. but if you are.. do that stuff: then if that doesn't do it.. make her "pay" you to reinstall windows
