Did you uninstall the older WinPcap completely - *including* any header
files or libraries from the developer's pack?

At least on non-WAN interfaces, yes; it didn't work with WinPcap 2.02,
but it *does* work for me with WinPcap 2.1 on Windows 2000.
However:

"Q-3: Can I use WinPcap on a PPP connection?
A: We have tested WinPcap on PPP connections under Windows 95 and
Windows 98 and it seems to work well. Under Windows NT and Windows 2000
there are problems with the binding process, that prevents a protocol
driver from working on the WAN adapter if it is not written by
Microsoft."
so if you're capturing traffic on a dial-up connection rather than, say,
an Ethernet LAN, there may be *other* reasons, over and above the bug in
question, why you wouldn't be able to capture traffic.
