[Samba] NT_STATUS_INTERNAL_ERROR

[Ricardo Pardim Claus]

Dear,Samba updated to 4.4.5 version.The Samba is a secundary DC.I'm getting some authentication errors.
smbclient -k -L //domain.localsession setup failed: NT_STATUS_INTERNAL_ERROR
Using my PC when I try to access the \\sambadc, is asking User and Password.The logs appears this:
ctx setting sec (0, 0) - 0 = sec_ctx_stack_ndx[25/07/2016 14: 08: 04.581532, 5] ../libcli/security/security_token.c:53(security_token_debug)   Security token: (NULL)[25/07/2016 14: 08: 04.581539, 5] ../source3/auth/token_util.c:639(debug_unix_user_token)   UNIX token of user 0   Primary group is 0 and 0 contains supplementary groups[25/07/2016 14: 08: 04.581551, 5] ../source3/smbd/uid.c:425(smbd_change_to_root_user)   change_to_root_user: now uid = (0,0) gid = (0,0)[07/25/2016 14: 08: 04.581807 3] ../source3/smbd/server_exit.c:246(exit_server_common)   Server exit (NT_STATUS_CONNECTION_RESET)

What can be wrong in the settings?
