Came across a weird one a few weeks back. Had me head scratching for about 3 days.
The Problem
Get this – any time an externally connected Skype for Business user added media to a conversation – audio, video or screen sharing – the Edge server they were connected to would reboot every time! And, there were 2 Edge servers that did the same thing!!
Long story short, the issue came down to VMWare guest tools. For some reason the vShield Endpoint/Guest Introspection Drivers were causing this. I was lead here by the BSOD memory dump which mentioned the faulting driver was tdx.sys.
The Fix
On each of the Edge servers from Programs and Features, select “Change” then remove the “NSX File Introspection Driver”:
