I have a problem capturing on Windows XP. I'm running Wireshark
0.99.4installed using the Windows Installer package from
wireshark.org.

I'm using Windows XP Pro SP2 with all patches installed. I have tried
completely removing Wireshark & WinPcap, doing a double reboot, and
reinstalling but the problem remains. It is the very same issue reported
over 12 months ago here (
http://www.ethereal.com/lists/ethereal-users/200512/msg00091.html). I also
had that very same problem with Ethereal which is why I updated to the
latest Wireshark release. WinDump works fine allowing me to start multiple
captures one of the other.

I get a 50:50 chance of a hang when I start capturing. If the first capture
works the second (so far) has always failed. I have updated to the latest
NIC drivers and that hasn't fixed the problem.

My system details are XP Pro SP2, HAL
Version="5.1.2600.2180(xpsp_sp2_rtm.040803-2158)"
NIC=ASUSTeK/Broadcom 440x 10/100 Integrated Controller - driver bcm4sbxp.sys
V4.47
I do have a Cisco VPN client V4.0.4(B) and Microsoft Virtual PC 2004
installed, but Ethereal has been working in the past with these products
without any problems.

The fact that WinDump works OK would seem to lead one to think that the
problem lies somewhere within Wireshark and that is also what the WinPcap
FAQ's state. However the fact that the whole machine freezes (mouse cursor
stops moving, keyboard CapLock, NumLock, ScrollLock keys no longer toggle
the LED's and the reset button is the only option) would seem to suggest
that the problem in fact lies within a driver somewhere. Maybe Wireshark is
passing bad data to the WinPcap driver?

Does anyone have any suggestions as to what I might try next?

Many thanks
Ian
