Question : Can ping everything and can browse LAN but cannot browse the Internet with IE

I have an XP Pro user with docking station on a laptop that can successfully ping www.yahoo.com, and 4.2.2.2 and can type \\server1 and see shared folders on the LAN.  However, when opeing IE, the bowser will go to the home page one time, then slows to a crawl when trying to browse a different page then finally the browser just won't open anything.

And in case if u still face problems in dealing with it, just analyse ur log at the above site, and then scroll down where u will see a Save Analyse button, hit it and it will save ur Log Analysation, then copy the link of that page and paste it here, and we will check it for u :)
