Hello Iam have samba 2:3.2.5-4lenny7 installed on debian I have windows 2008 server configured as Active Directory Domain In security reason (malicious attack and absence microsft path to save system) iam disable 445 tcp port on my windows 2008 server Therefore users in my domain cant enter to samba file server. In samba logs there is error: [2009/10/30 14:40:11, 1] smbd/sesssetup.c:reply_spnego_kerberos(474) Username DOMAIN\usr is invalid on this system When i try shareserv:/var/log/samba# wbinfo -t Iam see: checking the trust secret via RPC calls failed error code was NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND (0xc0000233) Could not check secret Iam add this string to smb.conf file smb ports = 139 But users cant connect to samba. Strange as it may seem, but users with windows workstation can login/logout to any windows share server, even disable 445 port in all windows computers (servers/workstation) How i can work with samba server with disabled 445 port on active directore server ? Thanks
