[Samba] Samba3 PDC and Windows 8 RTM

[Didster]

Hi there,

I have just purchased a new PC that came with Windows 8 Pro (Shudder...).

I have been trying to add this machine to my Samba3 based domain.

I'm getting the following error when doing so:

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>

I have applied the Windows 7 registry patches:

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

Which others seem to suggest work - at least with Beta versions of Win8 -
but the error message suggests these are not doing anything?

I have also specified the DNS suffix of the network manually.  I have also
applied all available Windows updates.

Its Windows 8 Pro (on a Dell machine, if that matters) and Samba 3.6.6-3
running under Debian Wheezy.  Nothing at all in the Samba logs - but I
guess thats as its not even trying NT4 domain style.

Any help appreciated.
Thanks
Simon
