Hai James,

What is the connection's DNS suffix of the pc?
And did you setup TLS in you samba?


Look here, in the advanded tcp settings of the pc.  ( or ipconfig /all )

And is it ticked "Use this connections dns suffix in dns registration"
(In dhcp option 81.)

Or use Group policy editors.
- Computer Configuration\Administrative Templates\Network\DNS Client
	-Connection Specific DNS Suffix: enabled, and set to your.domain.tld
	-Register DNS records with connection-specific DNS suffix: enabled
	-Register PTR Records: enabled
	-Dynamic Update: enabled

Or use static ips, then A and PTR are registered by the computer.

Key is to remember, Windows uses the connection-specific DNS suffix to register
DNS records.


Greetz,

Louis
