WireShark: The NPF driver isn’t running

After you install WIRESHARK , you will receive the error “The NPF driver isn’t running” and there is not interface for trace. This is because the NPF service is not runnig by default.

To check the NPF service if running, you can run a command in command prompt (by Administrator)

sc qc npf

The output as below mean that the service will not auto start but manual start

C:\Users\KCYEAP>sc qc npf
[SC] QueryServiceConfig SUCCESS

BINARY_PATH_NAME : system32\drivers\npf.sys
TAG : 0
DISPLAY_NAME : NetGroup Packet Filter Driver

So you need to start the service by

sc start npf

For set it to auto run, you can use the command

sc config npf start=auto
