I changed my ISP this week, and now Internet isn't working on Kubuntu 6.06. The ISP doesn't support DHCP, so I had to manually configure the network settings (IP, netmask, broadcast, gateway and DNS), but I can't browse or use IM or IRC.

From shell, I can ping IP addresses, but can't ping domain names. When I try use IP address instead of domain name on my browser, it ends up with a error page. I know this a DNS problem, but can't figure out what's wrong -- everything works perfectly on Window$ with the same settings.

Everything worked OK with the DHCP settings of my prior ISP, but can't figure out why it isn't working now.

Please help me out guys. I'm very frustrated.
