What IP address does your computer think is www.goldbergcoins.com? Run a command prompt (cmd.exe) and type 'ping www.goldbergcoins.com' (without quotes). My DNS gives me 209.222.0.237. That doesn't work. Just says it can't find it in different colours. Sorry, the website cmd.exe cannot be found.You need to run cmd.exe on your computer, not your browser. Use Windows key and r at the same time, type cmd.exe in the dialog box.
