I am running Windows XP SP1 and I have recently noticed a slow down in my general internet use. Whenever I go to a website, it always takes a very long time to find the host, but it eventually gets there. I am experiencing this with Firefox and IE. I am behind a NAT router with a cable modem, another computer on the network is fine. Is it possible to somehow reset the DNS settings? I have tried disabling TCP/ IP restarting then turning it back on, but the same problem occurs. Thanks, Sam
