Thanks to all that replied : Gerald W. Carter, Levent ... Actually, I'd already done what had been suggested ... socket address = 10.10.10.5 interfaces = 10.10.10.5/24 It appears to working now... I think my problems were two-fold : 1. I made separate locks directories : /var/samba1/locks /var/samba2/locks and specified them in the smb1.conf & smb2.conf files via the "lock directory=" option 2. I had a "bind interfaces only = yes" option set, which I removed This seems to have fixed everything Thanks to all. I have a second question though ... I'm using "security=domain" and it seems to work just fine... however, the log file shows errors trust_password_lock: cannot open file /apps/samba/private/SFWMD_HQ.CURLY.mac trust_password_lock: cannot open file /apps/samba/private/SFWMD_HQ.MOE.mac If I do the "smbpasswd -j sfwmd_hq -r b50apps1" I get the following dialog : cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT cli_nt_setup_creds: auth2 challenge failed modify_trust_password: unable to setup the PDC credentials to machine B50APPS1. Error was : NT_STATUS_NO_TRUST_SAM_ACCOUNT. 1999/06/09 16:38:49 : change_trust_account_password: Failed to change password for domain SFWMD_HQ. Unable to join domain SFWMD_HQ. The NT admins say the samba server has an account.... Any thoughts ?? Thanks again Mark -- ++++++++++++++++++++++++++++++++++++++++++ Mark S. Velasquez, M.Sc.
