19. "net use"
  1. Maps a Network, connections, displays data.
  2. Basic Syntax
     net use [drive_letter | device_name] [\ \computer_name\share_name[\volume]] [/user:[do main_name\]user_name

  6. Connecting to a "Network Share Drive"
    1. net use <drive_letter>: \\<computer_name>\<share_name> [/user: [<domain_name>\]<user_name> [<password> | *]]
       [/savecred] [/persistent:{yes | no}]
  7. Maping 
    1. net use P:\\SERVER02\Public /persistent:yes

      2. net use \\<computer_name> /delete
      3. net use P: /delete
      4. net use \\PRINTSERV\HP LaserJet /delete
    8. Managing Persistence
      1. Set all connections "net use /persistent:yes
      2. Set to off "net use /persistent:no
      3. List current persistence "net use /persistent
