Windows 8 can join to Samba3 domain?

A bug which prevented a Windows 8 developer preview client from joining an NT4 level domain such as Samba3 was reproduced.  This was found during the Windows 8 developer preview timeframe (September 2011) as we discussed at the SNIA SDC and AD Interop Lab in Redmond.  It was fixed subsequently and this was confirmed in Windows 8 beta which was publicly released as Windows 8 Server Beta and Windows Consumer Preview, 2/19/2012.

As with Windows 7, Windows 8 Beta does require the following non default settings.

   Windows 7 and Samba 3 interoperability;

        DWORD DomainCompatibilityMode 1
        DWORD DNSNameResolutionRequired 0

Hope this helps,

Per our earlier discussions, particularly at the event at Redmond in October, can you please advise what the status of Samba3 DCs and Windows
8 members is?
