Windows 10: BSOD Occurs on laptop After Connecting to Conference Tablet, Related to RNDIS Interface

My Dell laptop is running Windows 11 Pro 23H2, and it occasionally experiences BSOD blue screen of death when connected to a conference tablet, with a probability of about 20%. From the Windows memory dump, it appears to be related to RNDIS. We have another Asus laptop running Windows 11 Home 22H2 that has never encountered BSODs when connected to the same tablet. Since there are no errors or crashes on the tablet side, and the BSOD occurs on the Windows side, we have no way to conduct error analysis. Could you please assist us in resolving this issue?This is the analysis result of MEMORY

Windows 10 Blue Screen when connecting to an RNDIS device.

We have a (legacy) device that is connected to Windows XP systems using a USB RNDIS connection. The device is an embedded Linux controller that is used in power management systems. We have thousands of these devices in the field. They are happy and stable using RNDIS over USB to set up an Ethernet connection between a Windows XP machine and the embedded linux device.

On attempting to build a new 'system' using windows 10 & the existing device, we find that Windows 10 regularly blue screens during the initial RNDIS negotiation. The blue screen happens about 20% of the time. The blue screen happens a few seconds after the RNDIS negotiation.

This problem occurs on all recent versions of windows 10.

This problem occurs on a wide range of PCs & laptops from different manufacturers (including Microsoft surface laptops).

If the RNDIS connection succeeds, then the two devices are happy and stable. The blue screen only occurs during the initial negotiation.

On inspecting the Windows kernel dump we see that windows is complaining of a 'list corruption'. The windows kernel dumps do not have a consistent call stack. Our guess is that a corruption occurs, some time later when using a 'list' that corruption is detected, then windows blue screens.

When looking at the message logs on the device side, we see a successful RNDIS connection established before the blue screen (i.e. the RNDIS filter is set by the windows PC).

We have windows kernel dumps etc that can be shared.

We are at a loss to determine how to fix this as we have limited visibility inside the Windows 10 RNDIS driver.

Any help would be appreciated.

W10 laptop won't connect to network, but Android tablet wilI

I run Windows 10 on an old Dell laptop. This afternoon, I suddenly lost my Internet connection. I keep getting a message asking for the "network security key," which is, apparently not the same as the password. However, my Android tablet (on which I'm typing this) is connected to the same network. I have a few interrelated questions:

1. Why would my connection suddenly drop out like this?
   
2. What is the "network security key?"
   
3. How do I fix this situation?
   

Please explain things step by step.

Thank you.
