Hi, can anybody give me a help? I am using Ubuntu 10.04 LTS with Samba 3.4.7. My Windows XP Clients are working fine. They joined the domain and i can login as user and i get all my shares. On the Windows 2003 32-Bit Server, who also succesfully joined the domain, no userlogin is possible. I recieved error messages: The domain is not found nor a connection will be established. Here is my smb.conf and the log of my w2k3-server [global] adminusers = Administrator,root load printers = no usershare path prefered master = yes domain master = yes wins support = true netbios name = carhs5 server string = server5 logon script = logon.bat local master = yes workgroup = CARHS logon path os level = 99 security = user domain logons = yes oplocks = yes log level = 10 log file = /var/log/samba/log.%m [netlogon] comment = LogonService path = /etc/samba/logon/ public = yes writeable = no browsable = yes [2010/07/28 15:05:59, 3] smbd/process.c:1273(switch_message) switch message SMBtdis (pid 24808) conn 0x7f82c923ee10 [2010/07/28 15:05:59, 3] smbd/sec_ctx.c:310(set_sec_ctx) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2010/07/28 15:05:59, 5] auth/token_util.c:522(debug_nt_user_token) NT user token: (NULL) [2010/07/28 15:05:59, 5] auth/token_util.c:548(debug_unix_user_token) UNIX token of user 0 Primary group is 0 and contains 0 supplementary groups [2010/07/28 15:05:59, 5] smbd/uid.c:368(change_to_root_user) change_to_root_user: now uid=(0,0) gid=(0,0) [2010/07/28 15:05:59, 3] smbd/sec_ctx.c:310(set_sec_ctx) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2010/07/28 15:05:59, 5] auth/token_util.c:522(debug_nt_user_token) NT user token: (NULL) [2010/07/28 15:05:59, 5] auth/token_util.c:548(debug_unix_user_token) UNIX token of user 0 Primary group is 0 and contains 0 supplementary groups [2010/07/28 15:05:59, 5] smbd/uid.c:368(change_to_root_user) change_to_root_user: now uid=(0,0) gid=(0,0) [2010/07/28 15:05:59, 3] smbd/service.c:1240(close_cnum) taurus (192.168.0.24) closed connection to service IPC$ [2010/07/28 15:05:59, 3] smbd/connection.c:31(yield_connection) Yielding connection to IPC$ [2010/07/28 15:05:59, 10] lib/dbwrap_tdb.c:100(db_tdb_fetch_locked) Locking key E8600000010000004950 [2010/07/28 15:05:59, 10] lib/dbwrap_tdb.c:129(db_tdb_fetch_locked) Allocated locked data 0x0x7f82c92400b0 [2010/07/28 15:05:59, 10] lib/dbwrap_tdb.c:42(db_tdb_record_destr) Unlocking key E8600000010000004950 [2010/07/28 15:05:59, 4] smbd/vfs.c:753(vfs_ChDir) vfs_ChDir to / [2010/07/28 15:05:59, 3] smbd/sec_ctx.c:310(set_sec_ctx) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2010/07/28 15:05:59, 5] auth/token_util.c:522(debug_nt_user_token) NT user token: (NULL) [2010/07/28 15:05:59, 5] auth/token_util.c:548(debug_unix_user_token) UNIX token of user 0 Primary group is 0 and contains 0 supplementary groups [2010/07/28 15:05:59, 5] smbd/uid.c:368(change_to_root_user) change_to_root_user: now uid=(0,0) gid=(0,0) [2010/07/28 15:05:59, 5] lib/util.c:632(show_msg) [2010/07/28 15:05:59, 5] lib/util.c:642(show_msg) size=35 smb_com=0x71 smb_rcls=0 smb_reh=0 smb_err=0 smb_flg=136 smb_flg2=51201 smb_tid=1 smb_pid=65279 smb_uid=100 smb_mid=704 smt_wct=0 smb_bcc=0 [2010/07/28 15:05:59, 5] lib/util_sock.c:528(read_fd_with_timeout) read_fd_with_timeout: blocking read.
