Guest W10 Enterprise N crash (BSOD) (SYSTEM_SERVICE_EXCEPTION) on W10 Pro N host - italc vnchooks.dll suspected

[davidgaca]

Hi,

I'm using VirtualBox 5.1.8 (but with 5.1.6 I had the same issue) in a classroom environment of 15 student PCs running Windows 10 Pro N.

Windows guests (Windows 10 Enterprise N, and W2K12R2 with update) randomly crash with "SYSTEM_SERVICE_EXCEPTION" and tend to reboot and throw the same error again.

I'm attaching:

• full Virtualbox logs
• Windows 10 Enterprise N memory dump
• msinfo32 report about host hardware and system.

After reviewing the virtualbox logs, I suspect the culprit is "vnchooks.dll" of italc, but I have no experience in debugging this issues.

"00:05:18.632201 supR3HardenedErrorV: supR3HardenedMonitor_LdrLoadDll: rejecting 'C:\Program Files\iTALC\vnchooks.dll' (C:\Program Files\iTALC\vnchooks.dll): rcNt=0xc0000190

Thanks for your time and support!!!
