If WinPcap seems to be removed, but the issue is still present, look for the presence of a driver named npf.sys (C: Windows System32 drivers npf.sys). The installer looks for this file, and if it is found, the installation is aborted. Remove the WinPcap component completely from the computer, and then deploy the RSD sensor again. NetGroup Packet Filter Driver isn't installed with WinPcap on Windows Server 2008 R2 64bit. The NPF driver isn't running. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. A: This error is usually caused by an antivirus or antimalware software that incorrectly detects the WinPcap kernel driver (NPF) as malware. This is because in the past some malware tools have been developed over the WinPcap library. Sep 15, 2015  First of all why are you using WinPcap? What windows are you using?

You need to run Wireshark with administrator privileges.

1. Exit Wireshark.
2. Find Wireshark on the Start Menu.
3. Right-click on it.
4. Select 'Run as administrator',
5. Click 'Yes' in the user account control dialog.

It's really best not to run Wireshark as Administrator. See here for an explanation - bugs in the dissector can do a lot more damage when it runs as administrator. A better solution (offered here) is the following:

Npf Driver Wireshark

• Open a command prompt (cmd.exe) using the 'Run as administrator' option
• Run the command sc qc npf
  You will see output similar to this:

• If it looks like this, you will need to start the service using sc start npf
  so that it displays STATE : 4 RUNNING.

• To start the service automatically in future, use sc config npf start= auto
  (that space after the equals sign is important)

Run 'cmd.exe' as Administrator, and go

then

To make sure type 'sc qc npf', you will get the output:

RTI Protocol Analyzer with Wireshark uses the Windows Packet capture (WinPcap) driver called NPF driver when it starts to capture live data. Loading the driver requires Administrator privileges.

To cllear this error, you need to open the file called npf.sys which is located at

Winpcap Error Npf Drivers

in Windows 7. Follow the below guide to open the npf.sys file.

Firstly, make sure that you have installed winpcap, if you didn't install it, just go to its official site and download it for installation: http://www.winpcap.orgNext, find cmd.exe which is located at

in Windows 7, right click and 'Run as administrator'. When it opened, input net start npf, then the NPF driver is successfully opened. That is,the file npf.sys is opened. At last, restart Wireshark, it will be OK now.

Note:
If you are using Linux or Ubuntu, after WinpCap is installed, use the common ' >$ su Administrator ' to switch to the highest authority account, then input net start npf .

If you are using Windows XP, login with administrator account then open cmd, input net start npf. Iview media pro 3 download.

I'm running Windows Server 2008 R2, 64 bit on a Virtual Server. There I want to install Wireshark to capture some of my network traffic for debugging purpose.During installation of Wireshark and WinPcap I ran into some problems.

Winpcap Error Installing Npf Driver

I've installed the following packages:

When I try to run Wireshark I get the message: The NPF driver isn't running. You may have trouble capturing or listing interfacesAfter some research I tried the command sc start npf in a command prompt. But doing so I only get the result:

I also had a look at Device manager ->Show hidden devices ->Non-PnP-drivers to look for the NetGroup Packet Filter Driver. But I can't find it. If I have a look at the installed programs, WinPcap was installed without any problems.

Any hints what to try next or what I'm missing?

Do I need to activate some specific features on the server? A reboot after the installation didn't help.
