Printers Management : Win10x64 NOK, Win7x64 OK

@Jonathan-Cool said in Printers Management : Win10x64 NOK, Win7x64 OK:

I use -S with PSExec to run the xcopy with SYSTEM account.
I think, I don’t need any credentials because the share is open to anonymous users (public hidden read only share).

But SYSTEM user is local system only. I’m pretty sure it doesn’t have rights on remote systems.

If i try to access this share using \NAS\drivers_imp\ or @IP\drivers_imp, it’s works without any credentials

But who are you testing this as? SYSTEM or a domain level users logged into a domain computer?

as a test why not try something like command script

net use \\x.x.x.x\drivers_imp /user:domain\user <password>
xcopy \\x.x.x.x\drivers_imp\test.txt .
net use /del \\x.x.x.x\drivers_imp

just to see if it is a user permission issue. The other thing you need to know where . points to. I would maybe use the full path here like c:\drivers or some other existing path.

@Jonathan-Cool Do I see this right, confirm that Win10 is having that issue per se. Anyone an idea why SYSTEM user is not able to copy files from a UNC path?

Jonathan Cool

Just to help to debug : same problem on Win10 physical computer.
Exact version of Win10 during test : 1803, last updates 2018.11.15.

@Jonathan-Cool Are both WIN7 and WIN10 machines joined to a domain? Is the server that your drivers are shared on joined to a domain?

Jonathan Cool

Hi,
@quinniedid
WIN7 computer has joined the samba 3.x domain.
WIN10 hasn’t joined the domain.
Drivers are not on the domain server but on a NAS disk (anonymous share)

Jonathan Cool

Hi,
I’m sorry for the UP but the issue is still here
Can’t copy drivers with a Win10 v1803 computer …
am i the only guy use this feature (Printers management) on FOG ?

Sebastian Roth

@Jonathan-Cool To me this seems like a “simple” permission issue. What if you create a public share for this drivers where no authentication is needed? Not sure if I miss the point here.

quinniedid

@Jonathan-Cool Is your NAS also connected or configured to your samba domain?

Jonathan Cool

Hi,
@quinniedid Nope, the NAS is only on the LAN but not configured for the samba domain.

I tried a new simple test on the Win10 v1803 : if i copy / paste the drivers into C:\ and set the printer (on the FOG printer management), the printer is seen correctly on the win10 … and i can SEE the drivers in the “printmangement.msc” Windows tool … so, the culprit is the share … not the driver, not the ini file … just the share … OR Windows 10 configuration.

So, the drivers are on a Synology NAS with :

fog user (used to push FOG image by FTP)
guest user enable.
https://drive.google.com/open?id=1Rkkuvf221OG28hgBvZO4NbSs7TbSqjyh

The printer section on FOG :

Name : XXXX
Printer Port : IP_1xx.xxx.xxx.xxx
Printer INF file : \NAS…\HP_M402_DNE\hpdo602a_x64.inf
Printer IP : 1xx.xxx.xxx.xxx
Printer Model : HP LaserJet Pro M402-M403 n-dne PCL 6 (found into the inf file)

What can i try now ?

Quazz

@Jonathan-Cool Still seems to be a permission problem from what I can tell.

You can try to test by assigning a drive letter as the system user to the samba share and see if you can then access the files using the drive letter assignment.

Something like:

net use V: \server\share /user:name1 passw2
xcopy V:\drivers C:\drivers
net use V: /delete

I’m guessing if the W10 joined the domain that could work too.

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:

Jonathan Cool

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 ?

Quazz

@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 …

davido38

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?
