I'm sorry...I don't see a question.
It appears that you are not getting DNS from somewhere.
If you go to your network connections (easy shortcut - start, run, ncpa.cpl...right click on the adapter, go to properties), do you have an IP address in the DNS section, or is it set to detect automatically?
Does your network do DNS, or are you getting it from the ISP/internet?
Can you connect out? If you open a command prompt (start, run, cmd) and type ping and an ip address (4.2.2.2 is a good one), does it reply?
I think we'll need a little more information about your setup to hepl you out.
