NPF設定為自動開啟

http://ask.wireshark.org/questions/1281/npf-driver-problem-in-windows-7

應該是我換了新版的Wireshark和Wincap後，npf被設定成了demand start，
參考上面連結，很清楚的可以設定為auto-start。


Run a cmd.exe as administrator and run the command sc qc npf.

You should get some output like this:

C:\Windows\system32>sc qc npf
[SC] QueryServiceConfig SUCCESS

SERVICE_NAME: npf
        TYPE               : 1  KERNEL_DRIVER
        START_TYPE         : 2   AUTO_START
        ERROR_CONTROL      : 1   NORMAL
        BINARY_PATH_NAME   : system32\drivers\npf.sys
        LOAD_ORDER_GROUP   :
        TAG                : 0
        DISPLAY_NAME       : NetGroup Packet Filter Driver
        DEPENDENCIES       :
        SERVICE_START_NAME :
If your driver is not properly started, activate it with the command sc start npf

Finally, to start the service automatically, use the command sc config npf start=auto

Remember to run your cmd.exe as administrator when issuing these command.
