How can I prevent the 0x00011b error from reoccurring after applying a fix in a Windows 10 environment?

Once the `RpcAuthnLevelPrivacyEnabled` registry key is set to `0` on the print server, it should prevent the 0x00011b error from recurring for that specific shared printer configuration. You generally don't need to take further action to prevent it from re-occurring due to new Windows updates, as the registry setting is persistent. However, always ensure both print servers and clients are kept up-to-date with security patches, and consider more robust printing solutions like dedicated print servers or direct IP printing for enhanced stability and security in the long term.
