Hello everyone, ? I currently have a problem that is not blocking per se, but I do not understand, I regularly incorporated into my field of Windows 7 machines I regularly check the logs and I see this kind of logs that is repeated every time log a user with domain IDs: ? [2013/06/28 11:20:34.438214,? 0] rpc_server/netlogon/srv_netlog_nt.c:976(_netr_ServerAuthenticate3) ? _netr_ServerAuthenticate3: netlogon_creds_server_check failed. Rejecting auth request from client POSTE-DEMO-WIN7 machine account POSTE-DEMO-WIN7$ ? I do not really understand what is happening, but with the level of the highest log on Samba I have no more details. I recall that the user can open or properly ferner folders or files. ? Server version: Ubuntu 12.04.1 LTS server Samba Version: Version 3.6.3 ? Thank you for your help here quite a long time that I hang these logs. thank you in advance,
