samba - Jul 2014 - Can't access Windows Server 2012 as member of Samba4 AD domain

Hi all,

I have windows 2012R2 server joined to Samba domain, but I can't access 
any share from other workstations. Shares has set access to Domain users 
group...

- when i run net view \\servername or \\ip address I get system error 5
- when i run net use \\servername\share i get system error 1396
- when i run net use \\ip\share i get system error 1789
- when i access \\servername\share from this server it works.

Have you any idea, how solve this problem.

Thanks
