Thanks for the help. It is just a public internet server (Flyer) that I am trying to access. On ISP-1 I've pinged the mail server successfully but got no response from the BBC. On ISP-2 everything pinged OK. There isn't a proxy for either ISP. Also disabled Zonealarm with no difference. I've looked throught the config for Firefox and found nothing out of the ordinary, but the puzzling thing is that IE6 was simultaneously denied access when the fault occured.
