You have seen reports where? The 2.1.7 VPN Client version includes a
driver set that easily passes all Microsoft Winqual LWF certifications.
I'm inclined to believe that your workstation has an Ethernet chipset
with less than mature drivers or you have installed another LWF driver
that may interfere with the Shrew Soft driver ( ie, another VPN client
or 3rd party security software ).
I don't see any answer to Kevin's question about additional VPN client
software you may have installed on the machine.
