Problem
I can’t upload Printer Drivers with my Windows 10 Client
Environment
Windows 10 with Patch Update KB5006670 installed
Solution
Microsoft has created a bug with this update, which makes it impossible to upload a printer driver.
Uninstalling patch KB5006670 resolves this issue. But from our tests it was also possible to resolve the issue by running these commands on the target UCS server:
net rpc rights -U"$samba_account"%"$samba_pwd" grant Printer-Admins SePrintOperatorPrivilege
net rpc rights -U"$samba_account"%"$samba_pwd" grant Administrator SePrintOperatorPrivilege
Where "$samba_account" and "$samba_pwd" need to be replaced by administrative credentials (i.e. a member of the group Domain Admins). The currently granted privileges can be checked by running the following command, e.g. for the group Printer-Admins:
net rpc rights list Printer-Admins -P
