Searching Remote Machines
The Remote Machines button on the Locations ribbon is a comprehensive method for searching remote computers that automatically searches every physical drive on the remote machine. The first time you choose Remote Machines, the View and Manage the Remote Machine List dialog box will appear but once you have entered a scope of computers it will simply enable the Remote Machine search. If this option is selected, the Remote Machines button will be highlighted.
Note: After you have selected Remote Machines you will notice that the Browsers and Registry buttons are disabled. This is because when searching remote computers it is only possible to search their file systems. emails will also be disabled unless you have the Searching Additional Outlook PST Data Files or Searching MBOX Files for Personal Information settings enabled. You cannot select multiple buttons in the File Locations group. If you want to search multiple disparate locations, simply use the Custom Folders button.
