this is really the wrong list for this, so i have CC'ed the samba 
mailing list, please reply there.

You say you started with Win 2003, but was the domain initially 
provisioned on 2000k ? or does it have the 2000k dns ?

Hi Rowland,

this is a good question. Does this listing help or answer?

So, in answer to the question Olaf posed, yes it helps, he has the 2000k 
dns which isn't compatible with the Samba dns.

You have the 2000K dns, there appears to be nothing in ' 
CN=MicrosoftDNS,DC=DomainDnsZones,DC=omtn,DC=de'
