first, thought this might be of interest:http://microolap.com...cts/network/tcpdump/
its a version of tcpdump (well known commandline packet info tool for scanning network traffic, http://www.firetower...m/forum/tcpdump.html
), but compiled for Microsoft Windows using Microolap's own excellent packet sniffing engine.
free for personal use.
i also want to make a comment about microolap the company (http://microolap.com
They have gone out of their way to help me in the past with programming issues and general advice. Definitely a great company with some great people working for it - people who go well beyond the call of duty.
So if you are looking for database tools, a network sniffing engine or a mapping component for programming, definitely give them a visit.
I can't say enough good about them
