OK, or add and change this line to remove the 'dnsupdate' service?

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate, dns

I'm not using DHCP to update DNS... I don't use BIND.

The plot thickens... the lease is set for 6 hours and should a Windows Server be trying to update anything to do with a Samba 4 AD DC?!

Just to clarify, so far it's just 4 Windows Servers that are ADDING their IPv6 addresses.


It's just happened again, so I have logged in to the Windows Server and checked it's IPv6 address which bears NO resemblance to the entry in the Samba 4 DNS...

   Name=V-INT, Records=2, Children=0
     AAAA: 2002:8282:00ca:0000:0000:0000:8282:00ca (flags=f0, serial=110, ttl=1200)
     A: (flags=f0, serial=934, ttl=900)

actual IPv^ address = 'fe80::7c57:b0d5:d6b9:ecc%12'
