My brother got a lenovo laptop with Vista Ultimate. He has a desktop with XP Pro. On the XP machine can connect to the lenovo and drag/drop files no problem. If I am at the lenovo machine, it sees the XP box but gives me the //computename is not accessable.... error. Any ideas on how to get the vista (laptop) to connect to the XP machine? BTW no firewalls and both C drives are shared with all permissions.
