Thanks for the reply.

I already figured that out and have added these lines to smb.conf:

client min protocol = NT1
server min protocol = NT1

Everything now seems to be working again. I thought I posted a followup 
but that seems to have gone missing.

My original smb.conf didn't include any protocol statements. Even after 
I added them testparm didn't print them out. I expected to see that in 
the output.

What still I don't understand is why the two versions weren't able to 
negotiate a protocol between themselves.

Reading the release notes it seems that 4.7.6 includes SMB2 and that 
SMB2 was added as far back as 3.6.

I did understand the default was changed to SMB2 in 4.11
