Hello all,

we are using the WinPcap library to emulate the DLC
protocol on W2K/XP calling pcap_sendpacket and
pcap_next_ex.

Our console application is running as an NT Service and
everything works as expected. Except one issue, which is
driving me crazy. When a user logs off, the service stops.

I'm aware of the SIGBREAK/CTRL_LOGOFF_EVENT signals and
added any kind of signal handlers I can think of. The
signal handlers are executed and properly ignored. But
still, as long as WinPcap is used by the service, it
stops on logouts.

Removing WinPcap solves the problem and the service
continues to run.

Version information from from WinDump:
WinPcap version 3.1 beta3 (packet.dll version 3, 1, 0, 23),
based on libpcap version 0.8.1

Any hints are most welcome.
Thanks,

Harald Kipp
