I am having issues getting WinpkFilter 2.3.5 with Windows XP professional, SP1A with Hotfixes Q331320 running on a Dell4600 (P4-3.06Ghz, 512MB, IDE). The issue I am having is when XP starts and I log in, none of my application programs communicate (Web browser, Instant Messanger, etc), but DHCP works (ipconfig /release and /renew both work), and ListAdapters.exe work. PassThru.exe also shows packets ingress/egress. Any help would be appreciated.
I have gotton this to work fine on one other XP Pro computer.
That’s strange. Try removing the driver, perhaps you touched the configuration of your network (i.e. the gateway). Also try a traceroute to the internet and to ping the gateway or a host on the internet.
OK, I figured out what my problem was. I had Trend Micro Internet Security 11.20 antivirus installed on my Windows XP system. As a part of the antivirus software, it also included a firewall. Although the firewall was disabled, the drivers for it still loaded. To fix this, I renamed the following registry keys:
After I did that, WinpkFilter worked! Thanks to all that helped!
