I suspect that should have been stated as "after installing WinPcap on
Windows 2000".... Ethereal's just a user-mode application and does
nothing whatsoever to your networking stack configuration, so it's
*extremely* unlikely it had anything to do with the problem; it's
WinPcap that includes OS kernel code and that has to configure the OS's
networking stack to include it.

Try uninstalling WinPcap.
If the VPN client now works, your choices are
1) leave WinPcap uninstalled, and don't capture traffic with
Ethereal (without WinPcap, it can't capture traffic on Windows),
just use it to read traffic you've captured by some other
means;
2) re-install WinPcap, and don't use the VPN client (if uninstalling
WinPcap makes the VPN client work again, it would appear that
you can't do both at the same time);
3) un-install WinPcap when you want to use the VPN client and
re-install it when you want to capture packets;
4) report this to the WinPcap developers:
http://winpcap.polito.it/contact.htm
following all the instructions given therein, in the hopes
that they can fix the problem, and wait for them either to
say it's unfixable or to provide a version of WinPcap that
should fix it (and follow one of choices 1), 2), or 3) in the
interim).
