Analyzing the Data
After inventory collection is complete, you can review individual inventory files in Notepad. Each text file contains sections, such as ComputerSystem and IDEController, that represent a characteristic of the inventoried computer. Not every inventory file contains every section, however. For example, if you inventory a computer that contains a SCSI controller but no IDE controller, the corresponding file will contain a SCSIController section but won't contain an IDEController section.
Also, a system's OS version will affect the amount of hardware that the inventory file displays. For example, a Win98 system's inventory file won't contain a PhysicalMedia section because the Win32_PhysicalMedia WMI class is available only on Windows 2003 or XP machines.
Within the available sections, you might notice some items with values listed as Not available. This value occurs when a hardware manufacturer hasn't stored data for a particular WMI property or when WMI can't locate a property's value. . . .
<P>If you want the serial number look at the IdentifyingNumber property of Win32_ComputerSystemProduct. Works on most computers built since 2001. Older computers may or may not report their serial number.<B>--Bill Schalck, April 19, 2004</B></P>
