Windows 7 and Samba 3 interoperability

Updated: November 10, 2009

Applies To: Windows 7

This article applies to the following operating systems:

  • Windows® 7


Windows 7 cannot join a Samba 3 domain. When attempting to join a Samba 3 domain, the following error occurs:The specified domain either does not exist or could not be contacted.


Changes to Windows 7 require that new values are added to the Registry in addition to updates to Samba 3. The required Samba 3 updates are included in Samba versions 3.2.12 and 3.3.5.


In order to resolve this issue, update Samba to 3.2.12 or 3.3.5. In addition to the update, the registry changes that are required in Windows 7 to allow the joining of a Samba 3.2.12 or Samba 3.3.5 domain are as follows:

    DWORD DomainCompatibilityMode 1
    DWORD DNSNameResolutionRequired 0
