Join Windows 7 to Samba domain [Solved]

Windows 7 Registry settings

There are currently two registry settings required to be added on the Windows 7 client prior to joining a Samba Domain. These are:

        HKLM\System\CCS\Services\LanmanWorkstation\Parameters
            DWORD  DomainCompatibilityMode = 1
            DWORD  DNSNameResolutionRequired = 0

Samba also ships with a registry patchfile that users can apply directly. The patchfile can be found in recent Samba sourcecode: $SOURCE/docs-xml/registry/Win7_Samba3DomainMember.reg or in Samba Bugzilla here: https://bugzilla.samba.org/attachment.cgi?id=4988&action=view

Make sure to either reboot Windows 7 or restart the LanmanWorkstation service after setting these entries.

You will receive one warning about DNS domain name configuration after the join has succeeded:

   "Changing the Primary Domain DNS name of this computer to "" failed.
    The name will remain "MYDOM".  The error was:

    The specified domain either does not exist or could not be contacted"

This warning can be ignored or silenced with setting other registry keys.

Update: There is a hotfix available from Microsoft to address this, see this http://support.microsoft.com/kb/2171571 Knowledge Base article for details

Do not edit any other registry parameters (NETLOGON) that have been seen in the wild. If you have already modified your Windows 7 registry, please make sure to reset the keys to their default values.

If you have changed the NETLOGON Parameters, make sure and turn them back to ’1′ as shown below:

       HKLM\System\CCS\Services\Netlogon\Parameters
           DWORD  RequireSignOrSeal = 1
           DWORD  RequireStrongKey = 1
