[Samba] Error message in smbd.log.

[Meng, Andrew]

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)

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
