I downloaded EtherDetect packet sniffer tool to trace for packet flow. While installing it it also installs WinPCap tool also. Now i have both winpkfilter and winpCap network drivers. When i run the sniffer tool and then access the internet i am unable to access the internet. When i not capture i am able to access the internet. What could be the problem. Is there any compatability issue with both drivers or what else? Please reply. Otherwise suggest a packet sniffer tool which is compatible with winpkfilter also and able to work when try to capture packets with the sniffer tool. Waiting for reply.
