Hi Louis,
Thanks you for your quick answer.

Unfortunately the command is not recognised - it would seem that the Server
Manager Command-line tools are not available on
Windows Server 2008, only on 2008 R2 upwards!   So I set the SMB1 DWORD value to
0 in the appropriate key in the registry to disable SMB1.
That did not help at all - same failure notice.

I checked the Forest/Domain functional level using "samba-tool domain level
show" and indeed it is set to 2008 R2.   
There doesn't seem to be  any command to lower the Functional Levels in samba.
However, I found this:
https://blogs.technet.microsoft.com/aman/2012/12/28/step-by-step-guide-to-lower-
active-directory-functional-level/

Would this work?   For example, if I re-join my Windows 2008 R2 machine as a DC,
lower the functional levels of the forest & domain,
join my 2008 machine, then demote the 2008 R2 DC?
