Hi Your free network utility tools are great. Would it be possible to provide a U3 version in future? I have tried to create one using a U3 package creation tool, but it does not work. We need to playback captured packets on machines that we can not install any non proprietry software onto, as they run very intensive time critical applications. The ability to run the packet player temporarily off of a U3 stick would allow us to debug without having to install a seperate machine into the network each time we have a problem. Thanks.
