[Samba] Joining PC to PDC domain does not work

[Daniel Thielking]

Hi Colleagues,

we are using samba 4.1.12 on a CentOS 7 Server. We have two different 
networks first one 192.168.1.x and the second one 192.168.2.x. no 
firewall on the router.

We are using WinNT-domain. Not AD!

The samba server ist in de 1.x network and the client in the 2.x 
network. If i try to join then client to the server I get an error 
message that the client cannot connect to domain because auf dns errors. 
I pointed the Client to the same DNS-Server where all the other clients 
on 1.x subnets are watching but this solves not the problem. Do you have 
any suggestions?

Thanks for your reply!

Daniel
