KB5005102 was the last change/reboot done.
the servers go into the troubleshooting screen and will not boot into safe mode or last known good configuration
other none dc servers show different errors
a) server manager requires one of the following versions of the .net framework v4.0.30319
b) hyper v host is broken
dism /online /disable-feature /featurename:netfx4
dism /online /disable-feature /featurename:server-gui-mgmt
reboot
dism /online /enable-feature /featurename:netfx4 /all
dism /online /enable-feature /all /featurename:server-gui-mgmt
Install-WindowsFeature -Name Hyper-V -ComputerName sglocdemoc240a -IncludeManagementTools
---so for about 8 non dc servers. that works---
for my 2 dcs, they are now stuck in a windows troubleshooting screen. cannot enter safe mode. cannot enter last known good configuration. can boot into DSRM.
right now, I am running dism /online /cleanup-image /restorehealth
what else can I do to get out of this nightmare.
