I'm getting the following error on a couple of WinXP-SP2 machines:

Scanner(Error) : 035: Unable to find the Inventory policy. Associate the
Workstation object with an Inventory policy.

This is only happening on 2 machines, and I have tried deleting the WS
objects, and re-importing them. The policy works fine on all other
machines. Has anyone else run into this? Any ideas?
