Does samba use the Unix password file or the smbpasswd file for smbmounting other machines. This problem is only happening on one out of three Linux machines at the moment on all Linux machines encrypt passwords = yes security = user Using LM8.1 and Samba 2.2.3 I could smbmount both Linux and NT machines. But for some unknown reason I can still smbmount Linux machines but not NT machines, even though both username and passwords are the same on Linux and NT, in both the Unix and NT accounts and the smbpasswd accounts. I can also get access to shared files on a NT machine from another NT machine using the same username password that are common to all machines. I can mount shares on the Linux machine from any NT machine, but not the other way round. This problem is also screwing up printing to the NT machines. I used Ethereal and captured the packet that sent the password to the NT machine and it contains 'Ansi password' and 'Unicode password'. But looking at the smbpasswd file none of them match. Could somebody tell me the reason why two types of password are sent, which one is used by the NT machines and should they be the same as the encrypted passwords in the Unix/samba password files. many thanks Confused Ken
