[Samba] NT_STATUS_BAD_NETWORK_NAME

[Carl Carpenter]

I am trying to run Samba 3.0.24-11.fc6 on Fedora Core 6.  I've run across
two problems that are keeping me from being successful.

1.  IPTables.  Even when I configure it through Webmin to not run at
startup, it does anyway.  I consider this a minor problem, at least for now,
although I wouldn't mind some input on how to configure it to allow Samba.

2.  Access to shares.  We are running an NT4 network.  I have joined the
Samba server to the domain and can see it in the browse list on my XP
machine.  I can also see the shares.  However, when I double-click on the
shares, I am prompted for a password which fails.  I have been through Samba
Security and Troubleshooting guide from Linux Home Networking and numerous
other documents with no positive results.  This is the test that fails:

[root at custer www]# smbclient //Custer/Intranet -U ccarpenter
Password:
Domain=[HCCMHMRC] OS=[Unix] Server=[Samba 3.0.24-11.fc6]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME

This test works (Colnago being the PDC):

[root at custer www]# smbclient -L Custer
Password:
Anonymous login successful
Domain=[HCCMHMRC] OS=[Unix] Server=[Samba 3.0.24-11.fc6]

        Sharename       Type      Comment
        ---------       ----      -------
        Intranet        Disk
        IPC$            IPC       IPC Service (Intranet)
Anonymous login successful
Domain=[HCCMHMRC] OS=[Unix] Server=[Samba 3.0.24-11.fc6]

        Server               Comment
        ---------            -------
        COLNAGO
        CUSTER               Intranet

        Workgroup            Master
        ---------            -------
        HCCMHMRC             COLNAGO

My username on the NT4 network is exactly the same as on the Samba server;
however, I have no password on the Samba server.  I use this setup on
several other servers with no problem, which is part of the irony of the
situation.  I have another server running FC6 and the same version of Samba
and it works perfectly.  The only difference that I can tell is that I got
Samba working straight off the FC6 installation disks before doing any
updates whereas this time I did all the updates first.  I have checked for
the existence of a 'msdfs'; none could be found.  I do not have SELinux
installed:  

[root at custer www]# rpm -q selinux
package selinux is not installed

Testparm shows the following:

[root at custer www]# testparm -s
Load smb config files from /etc/samba/smb.conf
Processing section "[Intranet]"
Loaded services file OK.

[global]
        workgroup = HCCMHMRC
        server string = Intranet
        security = DOMAIN
        password server = Colnago
        log level = 3
        log file = /var/log/samba/%m.log
        max log size = 50
        preferred master = No
        dns proxy = No
        wins server = 192.168.0.7
        default service = Intranet

[Intranet]
        path = /var/www/html
        read only = No
        create mask = 0774
        directory mask = 0775
        guest ok = Yes

The actual smb.conf looks like this:

#======================= Global Settings ==================================
[global]
        protocol = NT1
        log file = /var/log/samba/%m.log
        dns proxy = no
;       load printers = yes
        netbios name = Custer
;       cups options = raw
        server string = Intranet
        password server = Colnago
        default = Intranet
        wins server = 192.168.0.7
        workgroup = hccmhmrc
        os level = 20
        debug level = 3
        encrypt passwords = yes
        security = domain
        preferred master = no
        max log size = 50
;       winbind enable local accounts = no


[Intranet]
        writeable = yes
        create mode = 774
        path = /var/www/html
        directory mode = 775
        guest ok = Yes

I am not using winbindd or ldap.  

Any help with this would be appreciated.  It's really annoying when my boss
sticks his head in the door every 20 minutes and says "Well?"
