what version of winpcap are you using? I remeber I fixed a problem like the one you describe some time ago.

I've tried write a NT Service which capture network traffic using WinPcap libraries. I use MS VS .NET 2003 environment. As type of my project I've chosen VC++ project for Windows Service. When I develop simple console application everything works properly, but when I try to develop service I stopped at

pcap_open_live(d->name, 65536, 1, 1000, errbuf);

function. It seems to be problem with this function becasue when I comments code  from this line to end Service work properly I think (it notes my logs into event log) But if I uncomment this line even earlier logs from capture function are not recording into event log.

I have suspicion that problem is with "d->name" and similiar references but I'm not sure and I don't know how to go over this.

Thanks ind advance for any help!
Best regards,
