Hi,
We have some VMs for one of our customers than keep stuck if we restart them, they will not show alt+ctrl+delete till you disconnect the network adapter, login to Windows and connect back the network adapter.
I updated integrator services on these VMs but same issue. Those VMs either Windows 2008 R2 or Windows 2008 or Windows 2012 R2 and Hyper-V hosts (HYper-V clusters) are either Windows 2012 R2, Windows 2016 or Windows 2008.
How can troubleshoot this issue?
