Tried with an MS-Windows version of tracert (ftrace), it was supposed to be able to set the ToS field. However it seems like when I run wireshark that the modified ToS field does not stick, it could be some Windows specific feature that simply clears the ToS field. I will try some traceroute tests on our Linux boxes next week when I really start working. It could be that this will do.

In some versions of Windows you have to change the registry to be allowed to set any TOS bits, perhaps this is what's missing?
