DNS lookup failed
My iMac connects to the internet through Wi-Fi, then I plug my PC (thru a LAN cable) to the iMac and share internet. When I had Snow Leopard it worked fine. But ever since I installed Lion I constantly get this "DNS lookup failed" and I'm not able to surf the web with my PC, even though my PC says it's connected (Network Connections).
Please someone help me out.
Thank you!
