Just upgraded the server from Debian Wheezy to Jessie, which replaced 
Samba 3.6 with 4.2.

Yes. That's what I was focussing on but I now think it's not the issue. 
Whacking log level up to 10 I do see the user. I think the 
[NTDOMAIN]\[]@[DELL] may have been related to the

guest ok = yes

in [printers]

So, I can log on correctly and also map shares after logon just fine, 
including my [home] share. So this problem appears to be solely an issue 
with my [netlogon]


rem @echo off
net time \\fleet /set /yes
net use /persistent:no
net use * /delete /y
if "%username%"=="administrator" goto p1
net use h: \\fleet\%username%
goto p2
net use h: \\fleet\root

(everything root.root, everyone has read permissions). Looking for some 
little change in the smb.conf docs between 3.6 and 4.2!

Yes, tried both those but now don't think they're related to the issue.
