Check this : How to get the Computer's Unique ID

Hard Drive ID (Volume Serial)

Finding a unique volume serial works very similarly and luckily a bit simplier:

ManagementObject dsk = new ManagementObject(@"win32_logicaldisk.deviceid=""" + drive + @":""");
dsk.Get();
string volumeSerial = dsk["VolumeSerialNumber"].ToString();

You can use motherboard serial number:

public static string GetMBSN()
{
   //Getting list of motherboards
   ManagementObjectCollection mbCol = new ManagementClass("Win32_BaseBoard").GetInstances();
   //Enumerating the list
   ManagementObjectCollection.ManagementObjectEnumerator mbEnum = mbCol.GetEnumerator();
   //Move the cursor to the first element of the list (and most probably the only one)
   mbEnum.MoveNext();
   //Getting the serial number of that specific motherboard
   return ((ManagementObject)(mbEnum.Current)).Properties["SerialNumber"].Value.ToString();
}

Use the computer name if they are all in the same windows network. Yes some times they could have same name, but to get access to each PC, the network will have unique names for each.
