Windows 10: Consistent BSOD's that stemming from SonicWall Global VPN Client

I have a Windows 10 Laptop (Dell) that consistently reboots when the user is at home and trying to get work done via VPN through the SonicWall Global VPN Client. There are 50 dmp files in the attached zip file, so plenty to analyze. From the ones that I looked at, all the fault modules seemed to be one kind of a networking driver or another.

What I'm hoping to figure out is what I can do about it. I know that the VPN client is part of the problem, but it is at the latest version available (4.9.9.1016). I'm hoping you fine folks could maybe point me in the direction of something else that I can do to fix the BSOD problem.

Thanks so much!

upgraded to windows 10, now no network hardware detected

To whom it applies,

The issue for me was caused by the global sonicwall VPN client. When Windows 10 upgraded, for whatever reason it replaced my network adapters with the sonicwall VPN adapter.

The solution was to revert to 8.1, uninstall the VPN client, and re-upgrade windows 10.

It's a known bug with the upgrade process and has happened to all of my colleagues.

Hope this helps...

 

Windows 10, tapisrv High CPU, and laptop docking with switching networks

It happens when I switch from home to office or office to home.

It also happened today after a reboot. In that case, at home, I opened up my VPN client (Dell SonicWall Global VPN Client), connected to the VPN, disconnected, and then TapiSrv started consuming CPU, even after the VPN was disconnected.

I don't always use the VPN when at home, but there's a chance that is the culprit.

Sonicwall recommends to uninstall all other VPN clients, is this a leftover file ?

Hope this give you some clues/startingpoint to fix this BSODproblem.

 

This is a fresh Windows 10 install from media created with MS's tools, so if the Citrix driver is in there, then the SonicWall install must have put it there. I'm guessing it's dependent on it. That Citrix link is dead.

I believe that it is normal for the SonicWall NIC to be disabled until it's called into use by the VPN client.

I'll get those Intel drivers updated for sure. Not sure how an old version got installed.

It might be worth noting, that I did the same bug check on some of the .dmp files. The latest one shows the same thing that you saw, but almost every one I tried had a different module at fault, but they were all networking related from what I could tell. Not sure what to make of that info though.

 

Updated LAN and WLAN drivers and there was no blue screen this weekend. Hopefully we're over the hump.
