<div>I migrate to use Winpcap 4.0 .</div>
<div>
<div>When the Windows xp boot,and i enter the user password to login the windows desktop.</div></div>
<div>I found that the pcap_findalldevs function consume about 34 seconds.</div>
<div>My question is how long does the winpcap driver loaded ?</div>
<div>Does it loaded earlier than the network interface loaded?</div>
<div> </div>
<div>The program is prepared for a local network to authorization.</div>
<div>It is a radius client program </div>
<div>It doesn't enable IPv6 .</div>
<div>It doesn't enable wireless zero configuration service.</div>
<div> </div>
<div>My program is put into the windows system service.auto started.</div>
<div> </div>
<div>My environment is windows xp sp2 ,winpcap 4.0</div>
<div> </div>
<div>Thank you!</div>

<div><font size="2">This can be due to a number of reasons.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Do you have IPv6 enabled on your machine? this might slow down things a lot.</font></div>
<div><font size="2">Are you calling pcap_findalldevs from within a service that starts at boot time (maybe before you notify the SCM that the service is up and running)?</font></div>
