Sorry Michael, I was a bit inattentive when I replied to you before. The things are opposite: Traceroute uses UDP protocol, while Tracert uses ICMP echo request. They both elicit the ICMP expired on transit message when TTL goes to '0'. Some routers blocks UDP and doesn't send any ICMP answer to you, that is why tracert works with them. Fabio De Francesco
Really appreciate the response. I'll google for the patch you mentioned.
