I see that there is a registry override for this
Registry subkey
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
Value
RpcAuthnLevelPrivacyEnabled
Data type
REG_DWORD
Data
1: Enables Enforcement mode. Before you enable Enforcement mode for server-side, make sure all client devices have installed the Windows update released on January 12, 2021 or a later Windows update. This fix increases the authorization level for printer IRemoteWinspool RPC interface and adds a new policy and registry value on the server-side to enforce the client to use the new authorization level if Enforcement mode is applied. If the client device does not have the January 12, 2021 security update or a later Windows update applied, the printing experience will be broken when the client connects to the server through the IRemoteWinspool interface.
0: Not recommended. Disables the increase authentication level for printer IRemoteWinspool, and your devices are not protected.
I made the registry change on my Print Server (Server 2016) and was wondering if I need to do the same on all my clients?
I know this is not recommended but there seems to be no good information on how an organization that has been using a Windows Print server for years can migrate to a solution that is more secure. If someone knows of some good step by step instruction that can guide people to deploying printers to clients in a more secure way I am all for it. Preferably something that does not require confusing scripts and PowerShell.
