Stumped by only one computer unable to access web sites.
Computer A is running on the USB port of a Toshiba cable modem. Computer B is running on the NIC port of the same cable modem. Each computer has its own IP address. I have 3 web hosted sites that are not with my cable ISP. Computer A can access all 3 web hosting emails and web sites. Computer B can access everything on the internet except for 2 of the 3 web hosting emails and web sites. When I do a trace route from computer B to the web sites, it times out one hop before reaching the final destination. If I use computer B with my back-up dial account, everything is fine. I have used computer B for months without any problems. No software or hardware changes. The web hosting company does not know, the cable ISP does not know. So the question is why computer B can access everything except my web hosted sites? I am stumped at the moment.
