I am not using PPP. I have a cable modem. This computer is running Windows 2000. I just installed ethereal on the same local network on a PC running Windows XP and it works fine. I can't receive packets going to all computers on my LAN but that is probably a switch problem. But I would really like to get Ethereal to run on my Windows 2000 box. When I do my first capture things just stop working. I still have some type of access to the Internet and LAN (IE. ping) but I don't get regular network traffic anymore. All the other machines continue working fine.
Does anyone have any suggestions? This is really driving me crazy so any help would be greatly appreciated.
Thanks,
Dave

Are you capuring on PPP interface (e.g. dial-up)?

WinPcap 2.3 has several known problems with PPP and PPP support is disabled completely in WinPcap 3.0
http://winpcap.polito.it/misc/changelog.htm
"due to the large number of messages reporting problems (blue screens) with VPNs, PPTP and such connections, we have disabled the support for NdisWan adapters. As a consequence, it is not possible
to capture from PPP (neither NdisWanIp, nor NdisWanBh, nor NdisWanBfIn/Out...). At the moment we have no plans to fix the problem with VPNs, PPTP, PPP unless we get a generous sponsorship."
However there is a work-round that MAY work when using WinPcap 2.3.
