Microsoft's PrintNightmare update is causing a lot of problems with network printers
Dears, the latest Windows updates is causing a lot of problems with network printers mapped on a print server. Reference: Manage new Point and Print default driver installation behavior Managing deployment of Printer RPC binding changes for CVE-2021-1678 (KB4599464) The two recent patches (KB5004945, KB5004760, or KB5003690) causes these two main problems: 1) unable for users without administrative rights to install new print drivers. The end user receive this error 2) unable to use the print server with the new registry key RpcAuthnLevelPrivacyEnabled **The system logs reports this error: 0x0000011b** The two workarounds that you have to apply to survive and allow corporate users to be able to use the print server are: 1) Even if you have a GPO with "Point and Print Restrictions=disabled", you have to apply this registry key to allow non administrative users to install the latest print drivers from the print server HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint RestrictDriverInstallationToAdministrators = 0 2) Apply this registry key to disable the new default settings related to the print spooler vulnerabilities HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print RpcAuthnLevelPrivacyEnabled = 0 The above workarounds are only a temporary solution to survive and allow users to print. What is unclear to me is what should be the right way to manage these settings in a corporate environment without any end user interaction. So, if I want to be protected and apply the recent security fixes without asking the end users to do something, what should I do? Microsoft states that you need to set "RpcAuthnLevelPrivacyEnabled" to "1" on both Client and Print Server in order to be protected, but if you do this, you can't print. So, what should we do in a Corporate environment to be secure and print without any end user interaction about "driver installation" etc.? Thanks in advance
Printer drivers for Windows Server 2019
Hi, I am trying to install HP printer drivers on Windows Server 2019 (2 different office jet models), but they all say that they are not compatible with this Windows version (the setup is detecting Windows 10 64-bit as the OS). Any idea? Does it mean I can't use these printers with Windows 2019? Thanks.Printer Driver Error During Install
I have a Print Server running Windows Server 2016 where I have all my network printers installed. I have a Dell B1260dn, which works fine on the Print Server and my local PC. I have 2 Terminal Servers running Windows Server 2016 on the same network. When trying to add/map this Dell printer, I get the same error on both Terminal Servers. I have tried to clear from Registry but still did not work. Here is the error. Thank you for your help!
