hi, i keep getting http 400 errors with IE in vista home basic. I can can get on certain sites, google for example, but i cant get to for, instance My ebay. It seems links cause this too, for instance i got onto microsofts help page, but when i clicked on contact us the error came up again! Also i cant sign into windows live mail, i get error message 80048820 extended error code 8004841f. I think i may have altered a setting by accident because all WAS fine. Apparently my connection is fine, windows found no problems with it? Any advice would be much appreciated, cheers! Danny P.S it came up when i tried to post this too!!!! it said my browser sent a request that could not be understood? I had to go back a page and re-send? This is also preventing me running vista updates. Now noticed limewire cant connect either. On some site hitting refresh a couple of times work?? Alos getting a few of these: Bad Request (Invalid Header Name)
