We have a mixed environment with a Windows 2008 Server as a DC and Linux/Windows/OS X workstations/servers joined to the domain. The problem is the joins (domain memberships) are OK, browsing works, PAM authentication on Linux based on winbind works but some (not all) Linux computers are not showing in the master computer browser for the domain.

All of our Linux servers/ workstations are running CentOS 5.8/RHEL 5.8/ CentOS 6 or RHEL 6. This is the nbtstat output of a Linux server that works:

C:\Users\rchhetri>nbtstat -a xlxudt

Local Area Connection:

And this is for a server that does not populate the computer master browser:

C:\Users\rchhetri>nbtstat -a xlx0

    Host not found.

The command completed successfully.

The samba configurations for both servers are same. We are also running a wins server in the DC. From our samba clients, this is for the one that works:

smbclient -L localhost -U rchhetri

Our samba configs are same but the samba versions above are different (3.0 and 3.5). We have another Samba 3.5 domain member that works perfectly.

Steps that I have done:

  1. Confirmed that both forward and reverse zones in the DNS of the domain are populated.
  2. Even added static wins entries to see if it works.
  3. Rejoined all domain members with this problem to the domain
  4. net ads dns register for all domain members with problems.

What should I do next to solve this netbios problem?

Thanks John K. We have a Samba domain member server running 3.5 that works perfectly. We only have one server running samba 3.0.33 - which I have shown above. I looked for the two strings that you mentioned in our samba logs but I cannot find them. Like I said, authentication and browsing works but members are not populated within the domain master browser. –  rchhe May 15 '12 at 18:00

1 Answer 1

Do you have any logs showing problems or errors with the member servers running Samba 3.0.33? Is this problem, by chance, occurring only on the older version or are both version exhibiting this behavior?

I know there are known issues with how older versions of Samba handle authentication with Windows Server 2008 up to version 3.3 We've had issues with that exact version of Samba (3.0.33) and our solution was to simply upgrade to 3.5. In our case, we would lose domain joins, or, just like you describe, the member server would not populate.

Errors we saw were "NT Missing Parameter," and "NT ACCESS DENIED" errors.
