Hi, I have a very, very puzzling issue. We have a laptop (Vista OS) (one of several) and this specific laptop can access local network resources (shares, etc., etc.) but cannot access the internet. It is only occuring with this laptop and is only ocurring on-site. If I take the laptop home, it works fine.
Basically, the network is setup as follows. Win 2003 DC, a firewall/router which has DHCP enabled. On the firewall router for the lan we have specified the DNS and WINS to point to the Domain Controller.
The laptop logs in to the local area network and works fine on the local area network but does not have internet access. Other computers on-site which are configured the exact same way work fine.
The only thing the user mentioned was that he was prompted this morning to change his network password.
Any help would be appreciated as I am spinning my wheels here.
