I can confirm that I seem to be experiencing the same problem. A few
days ago, printers published from Samba AD and installed via GPO refused
to install any more. This has been working fine for 6 months or so,
since I setup the AD, until a few days ago - all according to
In the Event viewer on the Windows client I get the following:
Source: Group Policy Printers
The user '<printer_name_on_samba_server>' preference item in the
'<my_printer_installation_gpo_name>' Group Policy Object did not apply
because it failed with error code '0x800704ec'. This program is blocked
by group policy. For more information contact your system administrator.
This error was suppressed.
Trying to browse for the printer directly on the Samba AD (from Windows
workstation) I can see it, but when I double-click on it, I get the
"A policy is in effect on your computer which prevents you from
connecting to this printer queue"
"Operation could not be completed (error 0x00000bc4). No printers are found"
(the error message varies from machine to machine).
My setup is:
Samba ADC + print server: Samba 4.6.2
Clients: Windows 10 Pro x 3
A Samsung and a Brother printer shared on the Samba print server
Disabling the "Legacy printer driver policy" completely seems to get
everything working properly, and the printers are installed correctly
again by the printer installation gpo.
Follow-up: After more tests, it would appear that a recent Windows 10
update has modified the behaviour of the two print server trust GPO's.
When I amended them to use the *non* FQDN name of my print server, they
started working again.
Has anyone else experienced similar issues? Or maybe my findings are
incorrect and the issue is somewhere else?
