AD-Takeover fails with Failed to commit objects: DOS code 0x000021bf
Failed to commit objects: DOS code 0x000021bf
It seems, that the databas of the active directory is not properly tiedied up:
samba-tool drs clone-dc-database "schein.ig" --server=< **NAME oder IP des AD** > -UAdministrator --targetdir /var/tmp/hq-AD --include-secrets
Unfortunately the solution is not known, when an existing Exchange Server was part of the environment. But without this try an integrity check, and retry the takeover or the script from the investigation part again.
We guess that the error message comes from deleted references
