What does this alarm message mean: "Collection 'Tempdb File Location' failed : Windows data is not available for the 'Tempdb File Location' collection"? (4270343)

The Windows connection hosting the monitored SQL Server Instance is not linked and hence no file location is available.  On the connection list, right-click on the SQL Server connection and choose "Properties |  Details."  Under "OS Details," choose the Windows connection from the drop down menu.  If the Windows connection is not listed in the drop down menu, you'll need to create one first in Spotlight.  Then come back and look for it in drop down menu.
