Hello, We use CIFS(2.2.12) on HPUX 11.00 and users are able to use the shared directories but we saw a lot of error message in log file like: [2005/02/07 11:26:50, 0] rpc_client/cli_netlogon.c:(246) cli_net_req_chal: Error NT_STATUS_INVALID_COMPUTER_NAME [2005/02/07 11:26:50, 0] rpc_client/cli_login.c:(47) cli_nt_setup_creds: request challenge failed [2005/02/07 11:26:50, 0] rpc_client/cli_trust.c:(141) modify_trust_password: unable to setup the PDC credentials to machine x.x.x.x.

The smb.conf is: [global] workgroup = COF netbios name = vobs1tst security = DOMAIN encrypt passwords = Yes password server = x.x.x.x username map = /etc/opt/samba/users.map wins server = x.x.x.x create mask = 0775 directory mask = 0775 oplocks = No kernel oplocks = No case sensitive = No preserve case = Yes local master = No [S1] comment = Storage Directory path = /S1 read only = No [$IPC] hosts deny = 0.0.0.0/0 Can anyone give me a clue why we saw those repeated messages? Thanks a lot, Andrew
