Windows computers can't resolve samba share names in 10.04

toshiro · 10-02-2010, 05:27 PM

After upgrading my ubuntu server from 9.04 to 10.04, the window computers couldn't resolve samba shared names anymore, the error code displayed by Windows was 0x80070035.

I was using the ubuntu server as a samba server, using 'share' as the security authentication method, it has been working very well under previous ubuntu versions but, after upgrading to 10.04, the windows computers can't access the server shares anymore; the linux computers don't have any problems (I can access the shares from linux).

As a workaround, I've added the name of the server in c:\windows\system32\drivers\etc\hosts; but I'd like to know how to fix the problem without modifying every windows computer.

Any ideas?

Thanks in advance for any help.

To fix the problem you need to determine what machine is doing Windows Name resolution. Under Windows this is the WINS server. Go to a Windows machine, open up a command prompt (Start,Run, cmd.exe) and type:

Code:

ipconfig /all

You'll see output that looks like this:

Code:

Windows IP Configuration

        Host Name . . . . . . . . . . . . : HOST
        Primary Dns Suffix  . . . . . . . :
        Node Type . . . . . . . . . . . . : Unknown
        IP Routing Enabled. . . . . . . . : Yes
        WINS Proxy Enabled. . . . . . . . : Yes

Ethernet adapter Local Area Connection 8:

        IP Address. . . . . . . . . . . . : 1.2.3.4.71

        Default Gateway . . . . . . . . . : 1.2.3.1
        DNS Servers . . . . . . . . . . . : 1.2.3.12
                                            1.2.3.145
        Primary WINS Server . . . . . . . : 1.2.3.12

The last line is the important one. I'm guessing that the IP address there is the IP address of the Ubuntu server in question. If so, then you need to figure out why the Ubuntu server isn't acting as a WINS server anymore. The process that should be running is nmbd. The command "ps auwx | grep nmbd" will tell you if it's running:

Code:

user@user-desktop:/etc/network$ ps awux | grep nmbd
user   7154  0.0  0.0   3324   800 pts/6    S+   16:36   0:00 grep nmbd
root  19151  0.0  0.0   8676  1604 ?        Ss   Sep15   0:28 nmbd -D

In this case it's process 19151. If nmbd -D isn't listed you need to figure out why it's not starting. You can run it from the command line:

Code:

sudo nmbd -D

and see if an error is reported.
