When adding a printer to a new Pharos Print Server, the Pharos Administrator might display the error message:

"Error adding printers in Administrator: Unable to load the list of print drivers. The RPC server is unavailable."

No network issues are apparent.
This occurs when the Printers folder is not visible on the network, because no printer has yet been shared on the system.

To resolve the issue, create a dummy printer on the new server and share it. The dummy printer can be deleted immediately, as long as the server is not rebooted before a real shared printer object (such as a Pharos Spool Queue) is added.
