I have two computers in the house that are networked via cable.(there is no router involved) The main computer has a speedtouch usb modem dialup to wanadoo 2 mb broadband. I can surf happily on both pc's until I connect up to my companies vpn. The main computer that the dial up in on, is ok when I change the Internet explorer setting's to the companies proxy server address. However the second computer on my home network cannot communicate with the main computer, therfore I can use Internet explorer or file share.

Can anyone help with this?
