The problem with turning off a DC and leaving it off for a period of
time is replication. Any other DC's will try to replicate to the DC
that is turned off and there is always the chance of accounts
etc that have been deleted on the running DCs reappearing when the DC
is turned back on again.

If you are going to turn off a DC for any length of time, then, in my
opinion, you should demote it.

No, they are the full logs from Windows 10. But they are redacted (I
changed the domain)

I can always reinstall it anyway, you are right.

I demoted it, removed it, checked all the DNS, etc...

I tried to rejoin, same error.
