The 'net start npf' command is sufficient to launch Wireshark with sniffing capabilities. I ran the 'sc query npf' to show details on the NPF driver. I ran the 'sc query npf' to show details on the NPF driver. Win 7, installed Wireshark, worked fine the first time the program is runned. Turn off the PC, turn on, start Wireshark and since then message “NPF driver not found” is shown.
- okay, I gave an attemp according to the above link, but no luck its still saying 'The NPF driver isn't running'
while dng I got this doubt after extraction Packet.dll has 4 difft versions (Packet_1.dll, 2, 3, 4) in that I opened properties and checked the details
(Packet.dll- NT5) (Packet_1.dll- Vista) (Packet_2.dll- Vista) (Packet_3.dll- NT5) (Packet_4.dll- NT4) so here first i copied the (Packet.dll- NT5) but didnt work so tried with (Packet_1.dll- Vista) and the other Vista one both but no luck
so do u have any idea which one exactly I ned to copy ???- I've fixed this via copy File and some Powershell stuff.
I've bypass that issue.
I've capture the wincap installation.
For a 32bits app running on a x64 OS, I've make a condition on the nfp.sys file, in order to copy the x64 amd sys file.
Then with a Custom Action, I created a service using SC DOS command.
' sc create npf binPath= system32driversnpf.sys type= kernel start= auto error= normal tag= no DisplayName= ' NetGroup Packet Filter Driver '
I used Powershell my CA. VBS script should be also working.

Where can I find WinPcap in system control, I assumed it is running as a service but it seems I am mistaken.
I started WinPcap via command line (source):
Before starting WinPcap Wireshark didn't show any capture interfaces and afterwards it does. So I assume it is running. But I can't find it in the services list of the task manager.
To narrow down the candidates I compared running services after starting and stopping WinCap but there is no difference.
How can I directly confirm that this 'service' is running on Windows 8?
MYSTERIOUS:
sc query
lists 85 services - none of which is 'npf' - but sc query npf
will find it.Raffael

Yes, you are right, WinPcap is a service (but mainly a driver), named
NetGroup Packet Filter Driver
.The fact is that it cannot be seen in the Windows Services Manager
.You can find it in the registry at :
Not tested, but it seems that you can change the way the service starts. Navigate to the registry key above. Then you will find a
REG DWORD
value named Start
. Values are :- Value
0x3
: SERVICE_DEMAND_START - Value
0x2
: SERVICE_AUTO_START - Value
0x1
: SERVICE_SYSTEM_START
Wireshark Start Winpcap Driver
In the doc they say that it's work only on Windows NTx, but give it a try ! On my system it is set to
0x2
.To view it in a GUI, goto (i am talking about
Windows7
, hope it will work on Windows8
) :- Run
msinfo32.exe
- Then expand
Software environment
- Then choose
System Drivers
Here you can get the status for
npf
service (but cannot interact with it)Edit :

You can use this from the command prompt to check the service state :
or this, to check specificaly if it is running :
Edit 2 :
Mysterious :
sc query
lists 85 services - none of which is 'npf' - but sc query npf
will find it.Seems normal. Regarding the doc this is the way
sc
works.By default,
SC
lists only services, not drivers.NPF
is more a driver.![Start Start](/uploads/1/2/6/0/126068193/312563453.png)
- To get all drivers :
sc query type= driver
(NPF will appears) - To get all (Services + Drivers) :
sc query type= all
(NPF willappears also)

Wireshark Start Npf Driver Manually
If you browse to the 'Run' dialog (windows key + s, then type run for windows 8.1+) and type 'msinfo32' this will open and advanced system information dialog. Expand 'Software Environment' then select System Drivers. If you click on the heading 'name' it will sort them in order and you should find npf present, with its status in the columns to the right.
