How to fix printers requesting administrator credits after the PrintNightmare patch


Some printers require administrator credentials whenever users try to print in Windows Point and Print environments due to a known issue caused by security updates KB5005033 or later that fix the PrintNightmare vulnerability.

This happens because, after installing these PrintNightmare fixes, only administrators are allowed to install or update the drivers through Point and Print.

The request for administrator credentials is automatically triggered in environments where the print server has a newer driver than the client attempting to print.

“Some printers in certain environments using Point and Print may receive a prompt saying,” Trust this printer “and requiring administrator credentials to install each time an application attempts to print to a server printer or a print client connects to a print server, ” Microsoft explains.

“This is due to a print driver on the print client and the print server using the same file name, but the server has a newer version of the file.”

The full list of affected client and server platforms includes:

  • Client: Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607; Windows 10 Enterprise 2015 LTSB; Windows 8.1; Windows 7 SP1
  • Server: Windows Server 2022; Windows server, version 20H2; Windows server, version 2004; Windows server, version 1909; Windows server, version 1809; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2

If you don’t use Point and print, you should not be affected by this issue and you will also be protected by default after installing security updates released since August 10.

Workaround available

Microsoft added that the known issue can be resolved by ensuring that the same version of the printer driver is installed on the print server and on all clients in your environment.

“Make sure you are using the latest drivers for all of your printing devices and, if possible, use the same version of the print driver on the print client and the print server,” the company said.

If updating the printer drivers in your environment does not resolve these printing issues, you should contact your printer manufacturer’s (OEM) support team.

Additional information on this issue is available in the Frequently asked questions section of support document KB5005652.

In related news, according to user reports, PrintNightmare security updates released as part of this month’s Patch Tuesday are also disrupting network printing.

Windows administrators experienced large-scale network printing issues after installing the patch for the last remaining PrintNightmare vulnerability.

BleepingComputer has contacted Microsoft with questions about these ongoing issues, but has not received a response.
