Problem with IE after downloading SP2

[hapeecamper]

Hi,
Since I downloaded SP2 windows update, I am now having problems with my Internet Explorer browser on BOTH of my computers and it seems to be getting worse each day. When I click on a webpage, it opens for a second then jumps to a "page cannot be displayed" Then if I click on the "Forward" or "Back" arrows and if the page opens for just a second, then I quickly click on the "Stop" button it will stay but only if I can catch it quick enough. Some pages open up ok, others won't. Even my home page on Yahoo is now doing this today. Also I noticed when I do try to open my home page on Yahoo, it flashes like it is trying to download but then it goes to the "Page cannot be displayed" Help I am frustrated! What can I do to fix this problem?
Thanks

Do you have a router?

Certainly sounds like a DNS error to me.

Tech-Recipes Post on the Bug

Somehow the PnP changed my router settings when I installed sp2. Very odd. I just changed the dns settings on my router back to what they were set originally and it worked.

Let me know if this helps...

I tried the suggestions but my IE is still having the same problem!
