1. Stop any applications that are using the WinPcap library.
2. Remove the key HKLM/system/curentcontrolset/services/NPF from the Registry.
3. Remove the files packet.dll and wpcap.dll from WINNT/system32.
4. Remove the file npf.sys from WINNT/system32/drivers.
5. Reboot your box.
6. Install the version of WinPcap you wish to use.

Subject: [WinPcap-users] Problem uninstalling Winpcap.

I originally used Winpcap beta. I uninstalled it and put in Winpcap 2.3.
 
Never seems to get packets in promiscuous mode.
 
I tried uninstalling 2.3 and it says: "Installation Log File Not Found!"
 
I noticed in the registry the path to NPF.SYS had "\??\" before it and NPF did not show up in driver list. I fixed that. Now it shows up but windump -D show "1." as network adapter.
 
My installation is goofed up. How do I manually uninstall winpcap completely?
 
I am using Windows 2000 Professional.
 
Mike
