Network Sniffer Code

It would be very useful to see some code for how to put an Ethernet card into promiscusous mode in a Windows environment since M$ figures if you don't buy a Server OS, you don't need to see your local packet traffic. I know this is possible, I just don't have even an idea of how it is accomplished.

You want WinPcap - see the offical website: http://netgroup-serv.polito.it/winpcap/ From the website: "WinPcap is an architecture for packet capture and network analysis for the Win32 platforms. It includes a kernel-level packet filter, a low-level dynamic link library (packet.dll), and a high-level and system-independent library (wpcap.dll, based on libpcap version 0.5). The packet filter is a device driver that adds to Windows 95, Windows 98, Windows ME, Windows NT and Windows 2000 the ability to capture and send raw data from a network card, with the possibility to filter and store in a buffer the captured packets. Packet.dll is an API that can be used to access directly the functions of the packet driver, offering a programming interface independent from the Microsoft OS. Wpcap.dll exports a set of high level capture primitives that are compatible with libpcap, the famous UNIX capture library. These functions allow to capture packets in a way independent from the underlying network hardware and operating system. WinPcap is released under a BSD-style licence."
