I did some more testing; I booted the PC (Optiplex GX150, W2K), logged on, and logged off.

All the services are started, including Winmgmt. If I then log on (without reboot) with a test user who has no rights other than normal user rights, the model and service tag are NOT logged. If I make the test user local administrator, and log on again (again without reboot), the model and tag ARE logged. So it's a rights issue. Has anyone else had this problem too? Is there a specific right that should be set so that users can read this info?
