Ethereal is at the mercy of libpcap/WinPcap, and libpcap/WinPcap is at
the mercy of the device driver for the networking device and the
networking code in the OS.

If you're not capturing in promiscuous mode, try capturing in
promiscuous mode; some drivers might not show outgoing packets to
capture programs unless the networking device is in promiscuous mode.

If you *are* capturing in promiscuous mode, the driver might *still* not
be supplying outgoing packets to capture programs.

There's nothing we (or the WinPcap developers) can do about the driver. 
I'd suggest asking whoever supplied the driver (Microsoft, or the
networking card supplier).
