I have same error with Windows 10 / Forticlient 7.0.2.0090. I got connected with the VPN server but when I pinging a IP address in the network I have connected with via VPN, I got the blue screen with the same ndis.sys error and then reboots.
Same. It works fine on my home desktop, but my work laptop (where I need it the most) does not work. I can connect just fine without issue 99% of the time, but as soon as I even ping an IP through the VPN it bluescreens.
