You probably need to add nameservers to /etc/resolv.conf. From your windows box, go to the command line and type ipconfig /all partway down should be line that says "DNS servers" and there should be like 3 IP addresses there. Write down the numbers.
Then in linux, edit /etc/resolv.conf and add a line for each IP address. Should look like nameserver XXX.XXX.XXX.XXX where the x's are the IP address.
