A network drive is a folder or drive on another device (on the same network as you) that you have assigned a drive letter to. While mapping a network drive can be done without knowing the IP address of the computer the drive is physically attached to, knowing the IP address of the computer can help you troubleshoot when you are unable to reach the network drive.
Click "Start" and then "My Computer," or double-click "My Computer" if it is on your desktop.
Click the network drive. It will be labeled (drive's letter) on "computer name" where the drive's letter is the letter assigned and computer name is the network name of the computer that the drive is physically attached to.
Click "Start" and then "Run." Type "CMD" (without quotes) and then press "enter." A command window will appear.
Type "ping computer name" (without quotes), where computer name is the network name of the computer your drive is connected to. The screen will display "Pinging x.x.x.x..." The "x.x.x.x" will be the IP address where the network drive is located.
