We have a client with Windows 2012 R2 Hyper V host server and 3 virtual machines AD AP and DN
A couple of weeks ago the client starting getting a black screen when using RDP to connect to one the virtual machines DN
The other machines work fine. Teamviewer to DN the mouse works fine.
I rolled back to a backup a couple of days before and the issue went away for a week, then appeared again.
Check windows updates and nothing was recently installed.
When attempting to RDP the system log below is generated. RDP tries to utilise this PS2 mouse driver which does not load and hangs the session just giving a black screen.

Task Category: (212)
The driver \Driver\mouclass failed to load for the device TERMINPUT_BUS\UMB\2&2c22bcc9&0&Session2Mouse1.
Connecting to the VM through hyperv manager has similar issue, screen shows and keyboard but no mouse.
Device manager shows other devices
Microsoft PS/2 Mouse
Standard PS/2 Keyboard
with warning message the drivers for this device are not installed.
Uninstalling and attempting to rescan hardware does not resolve - they they show as Unknown Device
running sfc scan did not fix (thinking maybe corrupt driver)
Trying to reinstall integration components says the same version is already installed.
Any other ideas before completely rebuilding the VM?
