Q: I am using Snort on Windows and receive an OpenPcap() error upon 
startup: ERROR: OpenPcap() device open: Error opening adapter What's wrong?

A: Either winpcap is not installed, or you are using an incompatible 
version. Try upgrading to the latest version (2.1 as of 4/11/01). It is 
available from http://netgroup-serv.polito.it/winpcap/

Greetings all,

I've installed WinPcap 2.3 and rebooted.  Then I used the Windows 
Installer for Snort from Silicondefense.com to install Snort (Snort1.7 
with IDSCenter 1.08d) on a Windows 2000 machine.

When I click on "Test Configuration" I get the same error as reported in 
the FAQ.  Any ideas?
