I have a handful of workstations that either have no PC model information or inncorrect model information. That is, the inventory field Computer.Model is either blank or has bad info (i.e., a Dell Latitude (laptop) reporting itself as a Dimension (not a laptop). After doing some looking through the inventory I realized that another inventory field, Computer.System.Model, contains the correct information.
The only place on the actual machines, or in Active Directory that I find the model information is in the BIOS - this seems to be where Computer.System.Model is getting its info. I confirmed on the test machines that I can easily access that WMI reports itself OK - this seems to be borne out by the correct information (including serial numbers) that is found under Computer.System.*.
Where is Computer.Model pulling its information? Why is it accurate for about 90+% of the machines, but not on others?
Thanks for your help.
