Can't connect to a specific website. in Networking, Email, and Internet Connections Posted May 6, 2008 Since you say you can access it from another computer I would say it's being blocked by something. Windows firewall maybe? Try turning off the firewall to test it. Try adding the site to your "trusted" web sites in Internet Explorer. Could also try adding the site to the "host" file. I don't use Vista so I can't tell you how to go about doing this. Just some thoughts on things to check.
