Hello again, good people of TechSpot. I have had several troubles of my own in the past and every time I have found an answer (of sorts) in here, and I thought I'd bug you once again... I have a friend at work who has a computer that is working fine by all standards, except that it cannot ping a certain IP address. Almost any address pings (we have not found but one that NEVER allows pinging from that computer). I wonder how could this be? My own computer pings the troubling address just fine. Any help would be greatly appreciated. Thanks in advance.
