I have a XP client on a SBS 2003 domain. I get handed an IP address. I can RDP to the PC and it can ping LAN IPs but it cannot connect to the internet. DNS on the server shows an A record in the Forward Lookup zone to the correct computer name and a PTR to the correct IP address that is assinged to the PC through DHCP. I have restarted the computer, checked to make sure the DNS and DHCP clients are running, there are no firewall rules preventing it from connecting, I have run Spybot and Malwarebytes and found no malware to be installed.
