Hello,
Recently I installed Ethereal 0.99 / WinPcap 3 then upgraded to the current
Wireshark 0.99.5 / WinPcap 4 on my Windows XP Pro laptop.
I have been using Cisco VPN for a while without any trouble. Now, the VPN
does not work on my network card but does work with my Wireless connection.
Is it possible that Ethereal/Wireshark/WinPcap damaged a driver or something
else that would muck up my TCP packets?
I uninstalled Ethereal/Wireshark/WinPcap and re-installed the Cisco VPN
client but am still getting the same results.
Any tips or pointers?
The following is a snip from the VPN log:
