[Gianluca Varenni]

Can you please log a bug report as explained here?

In particular I'm interested in the file called npf.reg

Have a nice day

  Are you running any antivirus/antimalware software on that PC?

    I'm getting an odd error when I try to run WireShark. So I started doing some digging and found that WinPcap 4.0.2 is not starting up.  I've used it plenty of times in the past on other systems, but on this specific box I get an error in the Event Logs that says:

    "The NetGroup Packet Filter Driver service failed to start due to the following error:
    This driver has been blocked from loading "

    So I tried to start it via command line with "net start npf" and got pretty much the same error of:

    "System error 1275 has occurred.

    This driver has been blocked from loading"



    Anyone have an idea why the drivers might be failing to load?



    This is on a Windows Server 2003 system running in a VPS.


    Thanks,
    Andy Merrill
