Yes I'm interested in all 'Unknown Drivers' i.e the yellow triangle in XP. They could be any type of device, it's just anything that's unknown to XP. I've looked through the different bits of information Lansweeper has recorded on a machine and it doesn't look like it's recorded it anywhere unfortunately
Driver information is scanned for some, but not all, items found in the Device Manager. It really depends on which specific drivers you are interested in. Display adapter drivers are scanned for instance and can be found in tblVideoController, but keyboard drivers are not.
I believe Tom is refering to Unknown Device that would appear in the Windows Device Manager (Yellow ! indicates this status for a hardware peripheral missing it's driver thus unknown device). See the attached screen capture (even if I have none missing)
It would be great to have a report that would flag the computer having a missing driver in their system configuration.
