[Samba] NT_STATUS_NO_LOGON_SERVERS after removing a DC and WERR_BADFILE when trying to remove broken DC

Situation: Trying to upgrade Samba from 4.1 to 4.5 without disruption
too much by adding new DCs and demoting old ones.

After bringing online the first 4.5 DC, I ran `demote
--remove-other-dead-server=` on that DC to remove one of the old 4.1 DCs
(held no FSMO roles). That seemed to run fine (the DC had been offline
for a few weeks at that point and I didn't want to restore it just for
demotion.)

At that point, some (but not all) of our file servers started throwing
NT_STATUS_NO_LOGON_SERVERS (smbd) and
NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND (winbind -P). Windows' RSAT tools
also completely fail to connect to the domain.

Some of the old DCs started throwing "Failed to bind to uuid
e3514235-4b06-11d1-ab04-00c04fc2dcd2 for
e3514235-4b06-11d1-ab04-00c04fc2dcd2 at
ncacn_ip_tcp:7e4973ba-4093-4523-a70f-7caa4845e34d._msdcs.ad.tao.at[1024,seal,krb5]
NT_STATUS_UNSUCCESSFUL" errors

Attempts to remove the new ADDC fail with "(2,
'WERR_BADFILE')".


So… How the fuck do I recover from this? What's even wrong?

This sounds like a very inconvenient way to update.

The --remove-other-dead-server should be used only for desaster 
situations if there is no chance that the DC can demote itself.

That's the way how to update Samba:
https://wiki.samba.org/index.php/Updating_Samba#The_Update_Process



 > So… How the fuck do I recover from this? What's even wrong?

1.) Stop using such words on the lists.
2.) Calm down.
4.) Verify that the clients use a DNS that is able to resolve
     the AD DNS zones.
3.) Check if there are some of the DNS entries of the removed DCs
     left. For example, the ones you created manually when you
     join a Samba DC:
     https://wiki.samba.org/index.php/Verifying_and_Creating_a_DC_DNS_Record
     Some further things to check are listed here:
     https://wiki.samba.org/index.php/Demote_a_Samba_AD_DC
     Verify this at least on the DNS server the clients are using.
5.) Tell us all steps you ran, that lead to this situation.
6.) Show us the full "samba-tool drs showrepl" output.
7.) Is replication working between the remaining DCs?


Regads,
Marc

We're moving all internal services to a new infrastructure, migrating
Samba to a new version is more an incidental bonus.

I can (temporarily) upgrade the old DCs if it helps with the migration,
but their whole infrastructure is going to be decommissioned soon™, so I
need the new DCs either way.

So I should recommission the old server, rather than upgrading the old DCs?

Nothing changed here, the clients use a dnsmasq that has all Samba DCs
as backend. If I remove the new DC from dnsmasq, clients work again.

All records are still there. So the remote demotion apparently didn't
work at all and failed silently.

1. Installed Debian Stretch on a new machine (Samba 4.5.6)
2. Prepared a join as per
https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory:

 – Set up Kerberos, confirmed with kinit

 – Ran `samba-tool domain join ad.tao.at DC
-U"ad.tao.at\sven.schwedas"
--dns-backend=SAMBA_INTERNAL`

 – I noticed a typo in the server's `netbios name` setting, corrected
it, and restarted the DC

 – Noticed I had problems with the LDAP SSL certificates for this node
and restarted it a few times while fixing that (paths, permissions, etc.)

3. Afterwards, everything seemed to work fine (showrepl showed
successful replication, DNS records were created, LDAP bind worked), so
I added the server to dnsmasq as upstream nameserver

4. Ran `samba-tool domain demote --remove-other-dead-server=GRAZ-DC-BIS`
to remove the old, dead DC. The command ran without any error messages.

5. At the same time, winbind started to sporadically fail on file
servers (timing was close enough that it /could/ be unrelated to the
demotion attempt.)

6. I tried to demote the new DC to restore the domain back to a working
state, received WERR_BADFILE

7. Removed new DC from dnsmasq, this seemed to mostly restore the
fileservers' winbind functionality for whatever reason.
> 6.) Show us the full "samba-tool drs showrepl" output.
Attached for verbosity reasons. graz-dc-bis has replication failures
because it is still offline, graz-dc-1b started showing replication
errors after attempting to demote it.
> 7.) Is replication working between the remaining DCs?
If showrepl is anything to go by, apparently yes. Nobody made any
further changes apart from the changes listed above.

Where did you change this, in smb.conf or /etc/hosts ?? 
By default netbios name is adapted from the hostname. 

If you changed the hostname you might have found the source of your problem.

[Samba] NT_STATUS_NO_LOGON_SERVERS after removing a DC and WERR_BADFILE when trying to remove broken DC

In the end I just upgraded all DCs to 4.5 and remote-deleted the broken
ones. Seemed to work without a hitch, manual removal was only necessary
to remove the IPs from DNS\_msdcs.ourdomain\gc\.

I'll try adding new DCs on a date that's not "Friday two hours
before I
disappear for vacation".

Apparently not, adding new DCs failed with "WERR_DS_DATABASE_ERROR".
`samba-tool dbcheck --fix` solved that.

With that out of the way, the join seemed to work.

• DNS records as per
https://wiki.samba.org/index.php/Verifying_and_Creating_a_DC_DNS_Record
were missing, after adding them, the replication is working as well.

• File server verified to work, including authentication.

• However, the server is still missing from the following DNS records:

 – Domain [host -t A ad.tao.at.]
 – LDAP SRV records [host -t SRV _ldap._tcp.ad.tao.at.]
 – KRB5 SRV records [host -t SRV _kerberos._tcp.ad.tao.at.]
 – …and all the others I can find in the MMC DNS snap-in (_gc, _kpasswd,
etc. pp.)

• Kerberos works, but I'm not sure it's actually using the new server,
given the DNS issues.


Can I just add the SRV records manually? Should this be documented in
the wiki?
