I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser. It seems that this problem is related to DNS because when I input an IP address directly in the address bar of my web browser, the web page can be displayed. However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?
My flatmate can open web pages on his computer. We share the same router. – Steven – 2011-01-07T14:05:35.753
@Steven - which shows that it sounds like the problem is to do with point 1 or 2 of my answer... it could be any of three items I said. – William Hilsum – 2011-01-07T14:34:37.407
My big-number ports are blocked on the router. – Steven – 2011-01-10T13:51:55.833
