Can you get a debug level 10 log from Samba, plus a wireshark
trace of this operation failing please ?

Great idea, Jeremy, but it has to come from the OP, Ralf Aumuller!

OK, after downloading WindowsPE 10 and installing it in a VM, I can
confirm two things, as standard it doesn't connect to a Samba standalone
server and adding 'server max protocol = NT1' to smb.conf on the
Samba server, fixes it.

I have the level 10 logs.
Jeremy, do you still want the wireshark trace ?

As I do not really know how to use wireshark and all the info I could
find expects the server to be running a GUI, I had a look on the
Samba wiki and found this page:
 
  https://www.samba.org/~asn/reporting_samba_bugs.txt
 
So basically following that, here are the level 10 log files, a pcap
file and the smb.conf I used.

Thanks a lot for that ! Can you log a bug at bugzilla.samba.org
and upload these files so we can track it ?

If you don't get to it today I'll try and get to it, but
having a bugzilla bug will allow us to keep all info on
the problem together.

Much appreciated Rowland and thanks a *LOT* for reproducing !

Jeremy.

Thanks Rowland, sorry for the delay in looking at this.

Can you get a wireshark trace of this client connecting
to a Windows server please ?

It seems to be trying to log on using a 'guest' connection,
and refusing to accept the reply we finally give to
the SMB2 sessionsetup.

Seeing a WindowsPE 10 -> Windows server trace would
help in me figuring out what is missing.

I'll try following up with this at the SNIA conf
next week if I can get a WindowsPE10 install.

Cheers,

Jeremy.

Hi jeremy, there was a very big hint in there ;-)

'As I do not really know how to use wireshark'

You tell me what to do and I will do it.
