I have a basic network with a Win2003 Exchange Serve for domain controller. Well, typically when a visitor shows-up I need to configure the DNS gateway for it to get internet access. I had a visitor come in today, plugged his laptop and before I could sit down and configure the DNS it gain network connectivity and was browsing the internet freely. Normally visitors got XP machines, this is a brand new Vista laptop& ideally we dont what that to happen. Is there something that Vista has that enables the laptop to gain connectivity like that? If Vista has that enhancement, how can I stop it from gaining access so freely?
