Olá!
Eu me chamo Edione.
Estamos com problemas no mapeamento das impressoras na maioria dos nossos computadores com Windows 10 e 7.
Informo que pesquisando na internet, vimos que esse problema de mapeamento é em decorrência de uma atualização lançada pela Microsoft.
Pedimos a gentileza que nos oriente em como resolver esse problema, tendo em vista que os nossos colaboradores não estão conseguindo imprimir, devido a falha no mapeamento das impressoras.
Desde já, agradeço!
Hi there,
Yes, this is a Known issue with Windows updates, and uninstalling KB5005573 from the print server has solved the problem.
This update has affected many users and I like to share the forum for the same issue https://docs.microsoft.com/en-us/answers/questions/553928/error-0x0000011b-no-workgroup-printer-access-it-wo.html?page=1&pageSize=10&sort=oldest
For most users removing the update has sorted this, there are also other GPO methods described in the article try your hands on them and see how it goes.
Hope this resolves your query!

The new Windows default does not allow sharing printers to Windows 7 from Windows 10.
There is a registry configuration to allow this configuration. This is the new Windows default.
Hi @EdioneCarlosNunesRibeiro-2868
Microsoft article here: https://support.microsoft.com/en-us/topic/managing-deployment-of-printer-rpc-binding-changes-for-cve-2021-1678-kb4599464-12a69652-30b9-3d61-d9f7-7201623a8b25
On the machine sharing the printer
Add
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print
Dword RpcAuthnLevelPrivacyEnabled
set the value to 0
Restart the Print Spooler
There is no need to add this configuration to Windows 7, the print spooler on Windows 7 does not support this new protocol which is why it will need to be configured as off on the server.
Aparentemente deu certo. Obrigado!
Quais impactos a criação dessa chave pode trazer?
Apparently it worked. Thanks!
What impacts the creation of this key can bring
@EdioneCarlosNunesRibeiro-2868
I did the Google translate on your message.
Creating this key will just cause the printer connection to use the methods and protocols in place since Windows Vista.
The new method protocol is only supported on Windows 8 and greater. This protocol method is NOT supported on MacOS so anyone with Macs will need to disable the protocol if they need to connect from Mac to a shared Windows printer.
But does the creation of this key cause any vulnerability in the network?
@EdioneCarlosNunesRibeiro-2868
The vulnerability which has existed since Windows NT 3.5, is that a Windows machine is able to connect to a Linux machine pretending to be a Windows machine with a shared printer and download a malicious driver to the client system.
The new protocol prevents the client system, the print server in your configuration, from connecting to the potentially dangerous shares on Linux.
Do you have Linux on hour network?
