Dear Mohammad, I'm not sure I get the whole picture but I thought I'd send you a tip for testing.
You mentioned 'pinging to yahoo.com' As an alternative: - Try pinging to a real IP address instead to eliminate any DNS problems. - In case ICMP is somehow blocked along the lines, try telneting to port 80 of a web server on the Internet. - Further try pinging to an IP of the "company's network" The composite result of those three tests can better help you corner the problem. Keep us posted!
