[Samba] [SAMBA4 RC1] Strange internal DNS behaviour

[Szymon Życiński]

Hello

I'm using samba4 rc1 since 2 months as PDC with samba4 internal DNS.
Everything works but i can't ping domain clients even from samba
machine. Clients are named as station00x.domain.lan where x is station
number. But even on SambaPDC i can't ping it with for exapmle:
ping station004.domain.lan or ping stacja003. Nslookup says that there
is no host like that. Funny becouse domain works ok, from machines
joined to domain i can't also ping other stations with their names.
Query to samba internal dns returns that the hostnames are unknown.

I need it to remotely shutdown computeres with windows shutdown command.

Any idea?

Can you check if the DNS entries for these machines exist in the active
directory? "samba-tool dns query" should be able to do that, or the
Windows DNS management snap-in.

Cheers,

Checked in snap in remote dns management and only hosts A records
visible are for server and my machine with remote tools. All others
does not appear on list.
My resolv.conf look like that:

nameserver 172.23.198.20
search 4lo.czest.pl.lan
domain 4lo.czest.pl.lan


I made a step from debug dns in howto and received error list below
(this is only a piece):

Googling didn't help. I don't want to blind update to RC4 becouse ale
i really need works ok. If the errors are solved in next RC releases i
can update, but i would be better to wait for final release.
