Wndows Workstation update DNS this domain. DNS mydomain.ru resolved.

Thanks in advance

You have 2 separate issues:
Samba and networking.
The dns updates are done by the dhcp server when the network starts, which has nothing to do with samba.
You need to set the network card to update the dns server in the networking section of yast (if you are using ifup) or in your network manager settings.
