Remove role fails

[AnGian00]

Hi. After having demoted local Active Directory domain controller and having joined a different domain, I'm trying to remove Active Directory Domain Services role altogether. But the role removal operation fails, with code 8000ffff.


Digging through CBS.log, I've found the following errors:

sfc /scannow

reports no errors.

running

dism /online /cleanup-image /restore health

does not improve things.

How can I fix this?

Thank you.
