[WinPcap-users] winpcap on XP eats up all ports

[Henrik Wendt]

Hi there,   We have been using winpcap 2.3 for a longtime now; both on NT, 2000,98 and XP without any major problems. Recently however running on my:   Microsoft Windows XP Professional, Version        5.1.2600 Service Pack 1 Build 2600   The npf.sys driver, (I think it must be that one) seems to eat up all my socket connections, after a 20 minuttes stress test on my network card. After that I cannot connect to either the internet or my database. As soon as the application using the driver is shutdown, everything works okay again.   I suspect that it might have to do with one of the recent updates to XP since the application is running smoothly on an unpatched XP.  I've also tried with the 3.0 alpha winpcap same bad results, and I've even tried with Ethereal an anylyzer program using winpcap, which also shuts down my internet connection. Ethereal says something like not enough kernelbuffer.   Any help gladly appreciated.     Regards Henrik
