Printers Management : Win10x64 NOK, Win7x64 OK

[quinniedid]

@Jonathan-Cool I find it very interesting that a SYSTEM account will work on Windows 7 but not Windows 10. One thing I would like to see is doing the same thing with PSExec running as the SYSTEM account and once you have that command window open change the directory to where you usually have the drivers dumped to. Run the xcopy from the NAS. I would be curious to see the behavior difference between Windows 7 and Windows 10.

Also, can you capture a screenshot of the security permissions of the folder specially on Windows 10 that the drivers are dropped into? Something like this:

Hi !
I’m back with the answers …

The win10 station and win7 station aren’t on the domain. Same with the NAS … but works win7 so … i think it’s not a domain issue. Isn’t it ?

@Jonathan-Cool Error 58 indicates this has to do with how Samba has changed between Windows 7 and Windows 10, specifically for security.

What Samba version is the NAS running?

Try logging in with Samba credentials to the share in the net use command instead of guest logon.

[Jonathan Cool]

Hi,

fog@fog-nas:/$ samba -V
Version 4.1.20
fog@fog-nas-44:/$ 

I will try ti logging with samba credentils asap …

Hi,

is the smb1 protocol enabled on windows 10 ?

by default it is not.

[Jonathan Cool]

@davido38 Yes, i enabled this protocol during my tests

[davido38]

@Jonathan-Cool
As-tu essayé de modifier la clef de registre windows 10

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

LmCompatibilityLevel avec une valeur 1 ou 5 ?

[Jonathan Cool]

@davido38
Hi,
I tried with LmCompatibilityLevel = 1 (already set) or LmCompatibilityLevel = 5 (i rebooted after modification) and no more success

[Quazz]

@Jonathan-Cool Did using samba credentials change anything?

Some news … weird … : see below … : on the Win10 1803 station :

@Jonathan-Cool Your NAS probably treats unknown users as guest users. I’m guessing it thinks of “system” and “admin” as existing users, thus rejecting them.

[Jonathan Cool]

@Quazz Hmmm, you right ! … seem to be possible !
I so close to resovle this issue … maybe, need to check the NAS configuration ?

[Sebastian Roth]

@Jonathan-Cool Possibly related?!? https://forums.fogproject.org/topic/12204/fog-powershell-not-copying-to-win32-grouppolicy-adm

[Quazz]

@Jonathan-Cool They may be reserved accounts which is why it trips up, I don’t think there’s much to change in the settings there, going with the Samba credentials route seems the best way.

If your Samba share is AD enabled then domain connected PCs will likely logon under their actual accounts when they try to connect to the share rather than Windows assuming you want to logon as ‘System’

Hi,
Today is a good day !
i tried a new test : i used an other NAS (Seagate) and created a public share.
With the same windows 10 station, i can xcopy files as SYSTEM and the printer was correctly installed.

So, now, on the Syno NAS, i will tried to join our domain … i will be back
