Hi I have tried to go on my computer today I am on dial up and have a wired modem and am running xp but every time I try to connect it keeps coming up with error code 721 remote computer would not respond:mad: have rung up my isp (tiscali) and they have told me to unplug everything check modem is working make sure everything is connected but nothing has worked in the end they have told me that it could be my installation disk but I am not sure as it was fine yesterday .If there is anybody out there that could help me that would be great.Thanks Katie
