 Hang on, we're talking about two different things.

"Oh how I yearn for a freeware packet filter on win2k that enables you to
log connection attempts"

 I'm sure SNORT logs that.

 In terms o packet filtering:
"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 0.6.2). The packet filter is a
device driver that adds to Windows 95, 98, ME, NT, 2000 and XP 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 directly access 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 well known Unix capture library. These functions allow to
capture packets in a way independent from the underlying network hardware
and operating system."

 Now I don't seem to be able to find a packet filter as such for it, but I'm
sure somebody must have created one... I understand your point and I'll keep
searching.
