Maybe it's not really doing a traceroute (since that requires some
privs).  Maybe it's doing something like tracepath under Linux instead?

Just guessing.

I think it's more likely that the Windows box is "different" from the
Linux box with regards to what is allowed though (talking about the
local security or lack thereof at the site).

It's NOT uncommon to disallow traceroute nowadays at the network
routers.  But that should affect all platforms...

Are you doing traceroute as root on Fedora?  Traceroute requires root
privs.  Maybe it's an selinux thing that's keeping it from working
correctly??

Again... just guessing...
