The SENTINEL error message showing the failure to add a printer.


This error occurred when a user tried to add a printer to SENTINEL. They were using a control variable command within the web services plugin. However, the web services command failed due to SENTINEL not being able to access the list of printers.


We identified the cause of the problem as being with the Print Spooler. Specifically, the Print Spooler was turned off and disabled. Once the Print Spool was set to “Automatic”, the “Add printer not completed…” error message disappeared.
