I tracked it down at last!
I have discovered through trial, error and chance (the Etherpeek support
pages) that the problem is indeed due to the SafeNet VPN client. Those of
you that use it, or similar, may have noticed that a 'Deterministic Network
Enhancer' component has been added to your NIC properties.
If you disable it for the duration of the capture, everything works fine
(you can leave the IPSecMon and IREIKE services running) - in W2K you don't
even need to reboot. However, you may need to reboot to get the VPN client
to work again...
This is indeed a WinPcap problem so I will be reporting it there also but I
thought as an FYI, it would be useful for all y'all here too since I only
found it by wanting to use Ethereal :^)
Regards,
Ade!
