Hi,
Has it worked for you in the past ? If so, the configuration is probably messed up. Delete the %APPDATA%\Unleash Networks\Unsniff\Cfg directory, and restart. You dont have to reinstall. (To open the %APPDATA% folder, use Windows Start->Run->Type in \"%APPDATA%\" into the box)
If this is the first time you are trying Unsniff and it is not working, then you can try a couple of things.
1. Go to \"Tools->Customize->Capture\", click on the adapters button. Do you see your network adapters in that list ?
2. Uninstall Winpcap (via Add/Remove programs), this will make you use Windows Raw Sockets as the packet provider. See if it works.
If still no luck, please tell us which version of Windows you are using (XP/2K/XP-SP2/Vista). Also, are you running under VMWare?
Thanks for this report, This is certainly a high priority fix for us.
Best Regards,
Vivek Rajan
