Microsoft traceroute (tracert) uses ICMP Echo-Request packets with a short TTL.

Hi everyone, in my firewall logs I see a lot of echo-requests within the internal network. Of course, the simplest answer to these events is that pings are causing these events. But on these machines definitely no pings are startet to that times. Is it possible that other kind of programs are using echo-requests? What kind of programs are using echo-requests and why? Checking wether the other host ist up? What if the firewall is filtering echo-requests? The program would think that the host is down... Greetings!
