Zentyal 7: Domain users always lose their "Desktop" etc. data; temp profile

[ATT1]

Hello,
I recently installed Zentyal 7 on a local server.
I have the following problem : Domain users can log in on a Windows-Client (usually, Win7 or Win10 Pro), but whatever they create in their profile is never properly saved. For example, one user can create a tiny folder on his desktop, but when he logs out and logs in again, the created folder simply vanishes. Sometimes, users are always logged in with a temporary profile and thus also lose everything they do on their profile, like, for example, Thunderbird settings, stuff on the Desktop, etc.etc.
In one case, a  Windows user logs in into the domain, but is automatically immidately logged off again. This even happens to him if the whole Windows-10-pro-client is freshly installed , so it cannot be because of some old registry settings, .bak registry settings, etc. etc.

Do you have any kind advice of how to deal with this and how to fix these bugs?

Believe it or not: I _still_ have the same problem, even with Zentyal7.0, with everything updated to all newest versions.
When studying the event log in the Windows-7-client, the Eventlog says "Error 1600 - no space on the Samba server" - which is not true: The server has more than enough free space.
Sometimes, also, the Zentyal server cannot be reached via ping etc. but using the "network repair" option (german: windows netzwerkdiagnose, "windows network diagnostics") sometimes helps for a real long time, but not indefinitely long. These bugs still reappear for years, and I am at a loss of what to do to fix them.

Please help !

Okay, I googled around more deeply and found a clue!
In the official Samba-Wiki it is mentioned that you can fix the rights of the sysvol stuff with :

Code: [Select]

sudo samba-tool ntacl sysvolreset
I did exactly that and the strange synchronisation errors , temporary profile problems etc. disappeared!
So I added this line into the crontab every morning at 06:00 am and so far my users' aren't complaining at the moment.

If all complaints are gone, I'll let you know!
