Are you able to use the Windows tools to open it remotely by UNC path using that user/password?
Do you see any other Internal events in the "LEM Internal Events" filter related to the connector after you configure and start it?
Anything of note in the agent's log (SWLEMAgent.log, or spoplog.txt, in the agent's running directory, usually c:\windows\syswow64\contegoSPOP\)?
Bonus points - on the agent, if you check out the file readerState.xml (in the tools directory of the above running directory), it's a big fat XML file but you should have a corresponding entry for this connector (search for NetApp) - for that entry, look for the logStartPoint and let me know what you see (e.g. logStartPoint="13456732").
