Hello!<br> -----------------------<br> PROBLEM OVERVIEW<br> -----------------------<br> I am using Win 2000 SP4 machine with a "3Com 3C920 Integrated Fast Ethernet Controller(3C905C-TX)" and Winpcap 3.0. <br> - When I run "windump -d", it lists no adapters. <br> - Ethereal does not list the 3Com adapter either.<br> - When I uninstall WinPcap 3.0 and install Winpcap 3.1, I see only a "Generic Dial-up Adapter".<br> -If I go back to Winpcap 3.0, I dont see any adapters listed!<br> <br> Anyone know why this is happening and how to fix it?<br> <br> -----------------------<br> ADDITIONAL DETAILS<br> -----------------------<br> <br> Here are details of how all this started and all investigation details.<br> <br> - I was able to capture traffic with WinPcap 3.0 on the 3Com adapter.<br> - There were some Symantec updates(anti-virus) pushed to my computer by my company. I am not sure if there were any further changes pushed during the same update.<br> - After a
couple of days, I realized that I do not see any adapters in the output of "windump -d" or even Ethereal.<br> - I unisntalled Winpcap 3.0 and re-installed Winpcap 3.0 to see if this fixes the problem but it didnt.<br> - When I install Winpcap 3.1 instead, I see that a "Generic Dial-up Adapter" is listed in the list of interfaces.<br> - ipconfig/all shows the 3Com adapter and I can connect to the internet successfully.<br> - I tried cleaning up Winpcap registry entries(Carefully) and also made sure that packet.dll and winpcap.* files do not exist on my computer before isntalling winpcap again. <br> - There were a couple of users who reported an issue with the SAME CARD on the ethereal mailing list but there was no resoution listed in the mailing lists.<br> http://ethereal.ntop.org/lists/ethereal-users/200009/msg00055.html<br> http://www.ethereal.com/lists/ethereal-users/200009/msg00036.html<br> - I have two other machines in my office with the same NIC and I
am seeing the same problem on both of them.<br> However, a third machine with same configuration on which "no Symantec updates were pushed". It seems to work fine. I tried to break this too by removing winpcap and No adapters were listed.But I was able to fix this very easliy with a re-isntall and I can see the 3Com adapter!<br> <br> <br> Nothing seems to work! Any help will be appreciated!<br> <br> Thanks,<br> -Jim<p>
