I have the same problem too. The difference in my situation is the fact that I am NOT a customer of BT Openworld, but Plusnet on a bt line.
In my office we use a dreytek2600. And I tried restarting that. Im running winXP sp1.
The funny thing is there are 6 computers in this network, but only two of the computers are redirected to 194.74.65.98, while the others are working fine.
I tried pinging in DOS: ping
www.google.com, but this actually pings the bt page. However if I type ping 216.239.59.99 (google's ip) this works as fine.
Also if I type
http://216.239.59.99 in the url field in a browser I can reach google.com. So it seems there is something wrong with the DNS or something.
The strange thing is that only two computers out of 6 are not working. I tried with both IE6 and Opera browsers and they are both affected.
I have looked on the internet and I can't find a solution. And unlike the previous post, I can't find where to download BT browser, and I'm not really keen on it either. (that shit software will probably set itself as default browser etc).
cheers
