What troubleshooting steps should be taken on the client computer when experiencing the 0x00011b error?

On the client computer, first ensure that all Windows updates are installed and that the latest printer drivers compatible with the print server are being used. Verify network connectivity to the print server (e.g., by pinging its IP address). Check for any local firewall rules that might be blocking RPC communication. Sometimes, simply removing and re-adding the network printer on the client can resolve minor connection glitches, especially if new drivers are installed.
