Yes. Both test hosts are using DHCP with static leases for IP addresses 
but not for DNS domains or nameservers.

Assuming you mean on the member, good point, but it doesn't change this 
behaviour. My understanding was this only affected smbd anyway, which 
I'm not running on the member.

No, this is just a default smb.conf from debian. I assume this wouldn't 
actually have any affect on a member server where there is no local 
passdb anyway and again, removing it has no affect.

No, these test hosts are very basic debian installs I've done to attempt 
to isolate this problem, although my "production" installs use SSSD.
