System Requirements

You *MUST* install the winpcap library (http://www.winpcap.org) for this version to work. tracetcp has been tested with version 3.0 and 3.1 beta 4 of this library.

Previous versions of tracetcp used raw sockets but Microsoft took out support for Raw TCP sockets in XP SP2, and as tracetcp uses this feature it caused it to stop working.

There is an article about this here that may be of interest: http://seclists.org/lists/nmap-hackers/2005/Apr-Jun/0000.html

In order to allow the program to function with XP sp2 it now uses the winpcap library to send and receive packets. The downside of using this is that the program will not function over dial-up connections. If you need to use the program with a dial-up connection then you can revert to the old raw sockets interface by using the -R switch (this will not work with XP sp2 of course)

tracetcp has been tested on on Windows 2000 & XP (It also probably runs on Windows 2003 but has not been tested on this platform). You must be logged on to the System as a user that has administrator rights to use tracetcp.

Note: tracetcp *may* work on Windows NT4, 98 or ME but has not been tested on these platforms, and I can offer no support for these platforms.
