Samba3 and Windows 8 RTM


So I have just got a new PC that has come pre-installed with Windows 8 (shudder...). The guy its for likes to live on the edge and wants to keep it, rather than just go back to Win7.

The network it is on runs Samba3 with a current mix of XP & Win7 clients. All Win7 clients have the compatibility mode registry keys set to join the Samba3 domain.

DWORD  DomainCompatibilityMode = 1
DWORD  DNSNameResolutionRequired = 0

With Windows8 however, it doesnt seem to matter what I try it always wants to try and join an AD style domain. With the registry keys, a reboot, and a join attempt I get:

The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "<BLAH>":

The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.<BLAH>

Some people seem to report success with Windows8 on Samba3. Does anyone know if this is still present in the RTM version of if its Beta/MSDN only?

Samba4 is not an option ;o)
