NIS not finding non-deletable desktop file

There is a (xsls) file that will not respond to Get Info or deleting it.  My new MacBookPro is crawling... crawling.  I have run NIS twice and it finds nothing.  The suspect file is on the desktop to the right...D719E300.  It takes several minutes to delete any file or move a file or rename a file...  This is very weird.   Thanks, Sandy
