We have a strange problem with 2 laptops (XP Pro). Working fine for some time, they suddenly were prevented from accessing network printers and drives. I was able to ping the domain server (Win 2000 Server) successfully. We don't use DHCP and have IP addresses set for each machine on the network. Going in to the network properties, I was able to get them to see the printers and drives again by changing one of the DNS addresses from our ISP supplied address to the address of our server. However that then prevented the laptops from accessing the Internet. Does anyone know what might be causing this? All other clients are working fine.
