[Samba] Unable to transfer ForestDns/DomainDNS

This is what it returned.

root at DC01:/mnt# ldbsearch --cross-ncs -H /var/lib/samba/private/sam.ldb -b
"CN=Infrastructure,DC=DomainDnsZones,DC=fisherthompson,DC=local" -s
base
fsmoroleowner
# record 1
dn: CN=Infrastructure,DC=DomainDnsZones,DC=fisherthompson,DC=local
fSMORoleOwner: CN=NTDS
Settings,CN=PDC,CN=Servers,CN=Default-First-Site-Name,C
 N=Sites,CN=Configuration,DC=fisherthompson,DC=local

# returned 1 records
# 1 entries
# 0 referrals


Looks right, right?  It almost seems like it is trying to delete it from
the Windows 2003 machine, but can't.  So I ran NetDOM /query FSMO on the
windows 2003 server and got this.

Schema owner                PDC.fisherthompson.local
Domain role owner           PDC.fisherthompson.local
PDC role                    PDC.fisherthompson.local
RID pool manager            PDC.fisherthompson.local
Infrastructure owner        PDC.fisherthompson.local
The command completed successfully.

So no DomainDNS or ForestDNS present.

Unfortunately that doesn't mean anything, the windows tools only seem to 
known about the five main FSMO roles (as did samba-tool up until 4.3.0)

Try this command, it should end with the word 'SUCCESS'

samba-tool ldapcmp ldap://dc01 ldap://pdc dnsdomain

Does the windows DC run a DNS server ?
