I try to go on the internet, i have comcast high speed. Sometimes it will work for about two websites for so, then it won't. It says I have shdoclc.dll/dnserror.htm . If i click "Detect Network Settings" it will work for another 30 seconds or so. I have no idea what to do! Also the only way to stay connected is go to my Network Connections, then Local Area Connection 2 Status, then Support, and i click Repair. Could someone help me? Comcast has provided no help whatsoever.
