What should I do if the RpcAuthnLevelPrivacyEnabled registry fix doesn't resolve the 0x00011b error?

If the registry fix doesn't work, try these steps: 1) Ensure both the server and client machines have the latest Windows updates installed (after trying the registry fix). 2) Verify network connectivity between the machines. 3) Check firewall settings on both the server and client to ensure that printer sharing traffic is allowed. 4) Reinstall the printer driver completely, ensuring no leftover files remain from previous installations.
