Blacklist HW

If the system detects obscure values during the HW detection, you can delete these values during detection processing. The database table intended for this purpose is tblWbemObjectProcess. The table contains some system values by default.

Table Description

Table columns:

txtCASS – shortened part of the WMI class name for the detected object – common values:
- DesktopMonitor – monitor
- BaseBoard – motherboard
- PhysicalMedia – harddrive (HDD serial number)
- NetworkAdapter – network card
txtPropName – Property name in WMI, e.g. SerialNumber, Caption etc.
txtPropValue – Obscure value detected, e.g. 000000 etc.
bolSetObjectAsVirtual – if this column contains the "True" value, the object will be tagged "virtual" – no corresponding object will be created in the Objects Tree, but the object will be still visible in the HW detection details. This is especially convenient if you are working with virtual CD-ROM drives etc.
bolClearObjectProp – if this column contains the "True" value, the value detected (obscure) will be replaced with an empty value during detection processing.

Note:

The columns bolSetObjectAsVirtual and bolClearObjectProp can only contain a pair of the values True and False.

Scenario: you have purchased a PC with a motherboard containing a certain serial number

The serial number is the same for all motherboards in all computers: 00000000. The detection reports a HW collision (detected components are located in a different PC).

Troubleshooting This Problem

Edit the table tblWbemObjectProcess, e.g. in Microsoft SQL Server Management Studio.
Insert a new row where:

txtCLASS – insert the following value: BaseBoard
txtPropName – insert the following value: SerialNumber
txtPropValue – insert the following value: 00000000
bolSetObjectAsVirtual – insert the following value: False
bolClearObjectProp – insert the following value: True

Save all changes.
Run a new HW detection evaluation for all computers which reported a collision due to the same motherboard serial number (00000000).
