[Samba] Fwd: Two DNS issues with samba

[Ronny Preiss]

Hi,

- I have changed my /etc/resolv.conf for all my three DCs.

### DC 01-03
nameserver 10.10.10.11
nameserver 10.10.10.12
nameserver 10.10.10.13
search intern.preiss.network

- In the next step I changed my /etc/hosts for each DC
### DC1
127.0.0.1 localhost
10.10.10.11     01-dc01.intern.preiss.network 01-dc01

### DC2
127.0.0.1 localhost
10.10.10.12     01-dc02.intern.preiss.network 01-dc02

### DC3
127.0.0.1 localhost
10.10.10.13     01-dc01.intern.preiss.network 01-dc03

As mentioned , I've installed a 3rd DC without any issues from
http://www.corpit.ru/mjt/packages/samba/.
Now the 3rd DC has the same Problem as the 2nd one.
Only the 1st DC has no issues.

/var/log/syslog

         ver.c:1076(dnsserver_query_zone)

I've recreated the dns.keytab file but this did not help.

### DC 01-03
samba-tool dbcheck --cross-ncs
Checking 3927 objects
Checked 3927 objects (0 errors)

### DC 01-03
No issues with samba-tool drs showrepl on all three DCs.
