samba - Sep 2017 - Antwort: Re: Windows 10 and Java Applications on a samba share

Hi Nils,
> one more information.
> This behaviour also happens on a WIndows 2012 R2 Server System.
if this behavior happens also on win2012r2, then the problem may be 
linked to the SMB version of the protocol.

Win7 support SMB version up to SMBv2.x, as does win2k8r2. On the other 
hand, Win10, Samba4 and Win2k12 supports SMB up to SMBv3.x. And protocol 
version is negotiated during connection to the max supported version.

You can check the version of the protocol used by the workstation with 
the "smbstatus" command. Could you try adding the following parameter
to
smb.conf and restart samba to see if it improves stuff

server max protocol = SMB2

By the way, IMHO running software from remote shares is a good way to 
look for problems. I would advise you to use deployment software to 
install your java program directly on workstation. You can take a look 
at www.wapt.fr, it is very easy to set up an internal repo and repackage 
business software (disclaimer: I work part time on that project). Note : 
there is a WIP German translation in WAPT, but you'd better use the 
English one for now :-)

Cheers,

Denis
