I don't know of any under a Windows environment - not even with Win Server 2003. There are in Linux, though, at least in my version (RHEL - Red Hat Enterprise Linux). The Linux version of Phex runs fine under it, but I know most people are running a Win variant (as am I, on most of my systems).
I will talk to some of my guys who are more TCP/IP literate than I am, and see what they have to say. Unfortunately, if you stay in IT long enough, eventually everyone else does the work and you just sit around signing things.
By the way, Cox has ceased their attack, at least for now. They kept it up for nearly a week.
Cheers,
Nick
