Presumably you're running on Vista, Windows Server 2008, a Windows 7  
beta, or possibly Windows XP with a recent enough service pack, so  
that you have the Native 802.11 support:


If so, then, if I remember correctly, the problem is that the WinPcap  
driver is an NDIS 5 driver, not an NDIS 6 driver, and doesn't support  
the calls required to capture in monitor mode:
