For more verbose logging on a particular switch discovery process do the following:
  1. Stop the MMS services on the site server using "stopmms " command.
  2. Open "ZENworks\mms\MWServer\properties\ " file on the site server and add the following lines "Discovery=DEBUG10 " and "SN3Agent=DEBUG10 " at the end of the file and save it.
  3. Start the MMS services using "startmms " command.
  4. From ConsoleOne, use step 1 and 2 to ensure "NCP" setting are unchecked.
  5. From ConsoleOne, select a switch node for which the display icon is not proper.
  6. Delete the node from "Database Object Editor " | "Delete ".
  7. From "Tools " | "Discovery Console " | Submit a Request for re-discovery giving the appropriate IP address and subnet mask.
  8. Wait for the discovery to complete and check if the newly discovered switch node is displayed correctly.
  9. sloader.log file will be available on server "ZENworks\mms\Logfiles\sloader " directory.
