I had version 2.02 of WinPcap, I don't think it was uninstalled correctly
before version 2.3 was placed over it. I uninstalled version 2.3, installed
version 2.02, uninstalled it, and reinstalled ver2.3. With many reboots I am
finally up and running. Thank you for your help. <sigh of relief>

If you do a Sonrt -W what do you get?
Grab a copy of Windump and run that and see if you can see packets
Make sure you have the latest release of Snort (
<http://www.silicondefense.com/techsupport/downloads.htm> )
Remove all of WinPcap 2.3 and use the one from our site. Be sure to reboot
after removal. There should be no difference but I've had reports of similar
problems (

If that all fails try removing WinPcap and going back a version to 2.2 of
WinPcap (search goggle?)
Note: If you are running a dual processor, you  MUST disable one processor.

something is wrong with my snort install, I get the error:
> Initializing Network Interface
> ERROR: OpenPcap() device open:
> Error opening adapter
> Fatal Error, Quitting..
 I have the latest version of winpcap installed.
if i change is to "snort -i 2" it gives me a no interface error, and the
"snort -i 1" gives me the error OpenPcap()..
I am really a newbie at this but maybe this might be a common error with a
quick solution. I am thinking that it is not liking the defaulted interface
but I do not know much about how to change it or even know what the good
interface is called..  
win2k server, snort 1.8.7, winpcap 2.3, 3com 10/100 etherlink XL
