Vote for tcpdump for Windows
MicroOLAP TCPDUMP for Windows reproduces all features of the original tcpdump by LBNL's Network Research Group , developed for the UNIX systems. Since MicroOLAP TCPDUMP for Windows is compiled with the Packet Sniffer SDK, it has the following advantages: does not require any third-party preinstalled drivers; works from the single 300K .EXE file; supports 1Gbit networks; may be launched remotely using Windows Terminal, Radmin , and other remote administration systems. Currently MicroOLAP TCPDUMP supports Windows 9x/ME/NT/2000/XP/2003/Longhorn.
