What should I do if the registry edit doesn't resolve connect to printer error 0x00011b on Windows 11?

If the `RpcAuthnLevelPrivacyEnabled` registry edit on the printer server doesn't resolve error 0x00011b, consider these alternative troubleshooting steps: 1. **Restart Both Machines:** Ensure both the client (Windows 11) and the printer server have been fully restarted after applying the registry change. 2. **Double-Check Registry Edit:** Carefully re-verify the registry key name (`RpcAuthnLevelPrivacyEnabled`) and ensure its 'Value data' is set exactly to `0` (zero) with no typos. 3. **Install Printer Directly (Local Port):** Try installing the printer directly on the Windows 11 client using a local port configuration and the printer's IP address, bypassing traditional network sharing. You will still need the correct printer drivers for Windows 11. 4. **Update Printer Drivers:** Ensure that the absolute latest printer drivers are installed on both the server and, if applicable, the client. 5. **Group Policy (Domain Environments):** In a domain environment, check if any Group Policies are overriding the registry setting or enforcing stricter print spooler security that might conflict. 6. **Microsoft Support:** If all else fails and the issue persists, consider contacting Microsoft support or your printer manufacturer for further assistance.
