it's normally blocked either by firewall or your ISP doesn't allow it..or you're behind a router thats blocks it.....try pinging me. go to start>run>type CMD
then in the command prompt type "ping 67.140.207.219" without the quotes
123ms is the average time. I do have a 'router' even though these home ones are not a router, with its built in firewall. I do not use any software firewalls.
