I wouldn't guess that, given that WinPcap-based programs (such as
Ethereal) can see outgoing packets on my machine at work, running W2K. 

I'll bet that one or more of those other pieces of software is causing
the problem; it's probably not the network monitor driver, as my machine
at work has that installed.  It's probably one of the other pieces of
software.

Do you have Network Monitor installed (not just the driver)?  Can it see
outgoing packets?

You should probably try this with WinDump:

and if it also doesn't see all the outgoing packets, you should try
reporting this to the WinPcap developers, using the "Reporting bugs"
instructions (including running the debugging version of packet.dll):
