I'm not a tracert expert and i've had some odd network behavior on my home system lately and ran it to see what was going on. I'm running XP sp2 with PCCillin 2005 (all pieces installed). With firewall up I can't tracert anything. With it turned off (XP firewall always turned off) I can tracert but the first hop times out. First hop should be my computer and I'm confused why it won't register. Is this normal? My ISP is Comcast and they were unable to ping my computer even with the firewall down.
