KB5005102 broke my dc's. they are booting only in dsrm mode. what to do?

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.

dism /online /cleanup-image /restorehealth has completed and upon reboot., its back to the troubleshoot screen.


I will try Dism /remove-package

May need to restore from a known good backup of a domain controller. The seize roles (if necessary)
https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/transfer-or-seize-fsmo-roles-in-ad-ds

then perform cleanup

https://techcommunity.microsoft.com/t5/itops-talk-blog/step-by-step-manually-removing-a-domain-controller-server/ba-p/280564

then rebuild the others from scratch.

yeah. unfortunately i thought there can be a fix but it seems to be borked up I suspect its because i have .net 4.8 installed.

the new servers i spun up do not have .net 4.8 and they completed all updates flawlessly.
