Hi, I have samba 1.9.17p4 on my Linux box (2.0.33), many Windows NT workstation 4.0, and a Windows NT server 4.0. My NT server has service pack3 and I set plain text password for it. If I set 'security=user' in my smb.conf, NT users can not browse any samba drives on Linux. I tried many different ways, and eventually found that ONLY 'security=server' AND 'password server=xxx', where xxx is the name of my NT server, can work. (That is, if I use my Linux box as xxx, it does not work.) It is okay if it does not show any problem. However, from time to time (once or twice a week or so) NT users still have trouble to mount samba drives. The log files show something like: switch message SMBsesssetupX (pid 16776) Domain=[MyDoanName] NativeOS=[Windows NT 1381] NativeLanMan=[] sesssetupX:name=[hongwei] password server MyNTserverName rejected the password 02/18/98 14:32:11 error packet at line 537 cmd=115 (SMBsesssetupX) eclass=2 ecode2 02/18/98 14:32:19 Transaction 11 of length 166 no matter how correctly I type my user name and password. I use the same password on Linux box and NT server. Then, I found if I kill smbd and nmbd on samba server, and restart smbd and nmbd, I can immediately mount samba drives without any problem -- I did not touch the NT server. Does anybody have similar experience? What is the actual reason for that? What is the best way to let samba run smoothly? I appreciate any information and help! Hongwei Li
