Idea
 For the workstation scan to execute successfully the following things need to be true: 
  1.  SSH needs to be running in the target Linux machines 
  2.  For Windows workstations 
    1.  The login provided for the network should have local administrative privileges 
    2.  Remote Registry service must be running in the target workstations 
    3.  Port 139 (File Sharing) must be open on the target workstations 
The scan report will display the total number of workstations scanned, the number of workstations successfully scanned, and the list of workstations that failed to scan.
 
You can track the status of the tasks assigned to the probe by clicking the settings icon against the network and selecting Task Status.
